Family teaches their rats to drive tiny electric cars because, oddly, it's good for them

It may look like a circus stunt, but a real study shows learning to drive is actually beneficial for rats.

Kuzko and Kronk love their "rat rods."

Some people look at rats and immediately get the willies, but people who've had pet rats know that they make delightful furry friends. They each have their own personalities and intellect, and if you get creative, you can teach the rascally rodents to do all kinds of fun things.

One of those fun things, which likely comes as an unexpected surprise, is driving. That's right, you can apparently train a rat to drive a tiny car. And the best part? It's actually good for them.

Before we get into the scientific research on that front, you simply have to see little Kuzko and Kronk behind the wheel (or pedals, actually):

 

Kuzko and Kronk's owners (@emperorsofmischief on Instagram) say it only took a couple of months of training 5 to 10 minutes a day for them to get the hang of the "rat rod" controls—three simple pedals that make the car go right, left, and forward.

"They do seem to enjoy their nightly practice," their owner writes. "We removed the back doors a while ago to give them full autonomy, and now when the cars come out the rats are quick to jump in on their own and hit the gas!"

The basis for even trying this in the first place is a 2019 study from the University of Richmond. Researchers taught 17 rats, some of them lab rats and some raised in "enriched environments," to drive electric toy cars in exchange for bits of cereal. (Those raised in "enriched environments" made much better drivers, in case you were wondering.)

The experiment continued after the study was published, and neuroscientist and researcher Kelly Lambert explained how observing the rat drivers early in the pandemic led to new insights.

"Initially, they learned basic movements, like climbing into the car and pressing a lever. But with practice, these simple actions evolved into more complex behaviors, such as steering the car toward a specific destination.

One morning during the pandemic, the rats also taught me something profound.

It was summer 2020, a period marked by isolation for almost everyone on the planet. When I walked into the lab one day, I noticed something unusual: The three driving-trained rats ran to the side of the cage, jumping up and down.

At that point, my lab started looking into how positive events — and anticipation for these events — shape neural functions."

Lambert and another researcher began a new study looking at whether anticipation (or delayed gratification). They called the research program "Wait for It," as they required the rats to wait a certain amount of time before engaging in tasks they enjoy. The results may hold some promise for non-pharmaceutical interventions in mental health challenges.

"Preliminary results suggest that rats required to wait for their rewards show signs of shifting from a pessimistic cognitive style to an optimistic one in a test designed to measure rodent optimism. They also performed better on cognitive tasks and were bolder in problem-solving strategies. We linked this program to our lab’s broader interest in behaviorceuticals, a term I coined to suggest that experiences can alter brain chemistry similarly to pharmaceuticals."

The initial study sound that learning to drive seemed to have a stress-reducing effect on the rats, with all of them testing higher in dehydroepiandrosterone, an anti-stress hormone, than controls.

Of course, that doesn't necessarily mean they like it. Rats do tend to thrive with interesting things to stimulate them, but one way to know whether the rats actually enjoy something is if they choose to do it instead of doing something that takes less effort. Lambert explained:

"Although we can’t directly ask rats if they enjoy driving, we created a behavioral test to gauge their motivation to get behind the wheel. This time, instead of giving rats only the option of driving to the Froot Loop tree, they could also make a shorter journey on foot.

Surprisingly, two of the three rats chose to take the less efficient path of turning away from the reward and running to the car to drive to their Froot Loop destination. This response suggests that the rats enjoy both the journey and the rewarding destination."

Enjoying both the journey and the destination is a goal for all of us, isn't it? Thanks to our rat friends behind the wheel, we may be a bit closer to figuring out how more of us can get there.

1 obvious and 4 not-so-obvious reasons your next car should be electric.

Yes, they cut back on carbon dioxide. But why else are electric cars finally getting the attention they deserve?

If you're not one of the roughly 85% of Americans over age 16 with a driver's license, you've still probably ridden in a car or bus in the past week.

And even more importantly, you're probably pretty familiar with the impact automobiles have on our environment. The EPA estimates that the average passenger car emits nearly 10,000 pounds of carbon dioxide into the atmosphere every year. For trucks and SUVs, that number goes up to over 13,500 pounds.

But what does a pound of carbon dioxide even mean? Well, the Natural Resources Defense Council put it nicely. "Filling a balloon with one pound of CO2 would swell the balloon to about the size of one of those rubber exercise balls that have become so popular lately. The balloon would be about two and a half feet across.


Now imagine 10,000 of those balloons in one place. And that's just from one single car.

Clearly, we have an issue here.

But here's something you don't know: something pretty interesting has been happening in the car world behind the scenes to fix this issue.

A lot of it involves Elon Musk going full-on Tony Stark, with giant robot arms and high-speed test drives and everything. Photo by Kevork Djansezian/Getty Images.

The electric car movement has grown by leaps and bounds.

Cars aren't really cars anymore. Sure, they're still meant for driving, but the machinery is making way for batteries. The hardware is moving over for software. The line between "car show" and "electronics show" is blurring.

And while we know that these computerized electric cars are the key to a more environmentally friendly future, it's always felt like some far-off technology that may or may not ever be ready for public consumption.

For some, going electric is just too expensive. For others, they worry the performance just isn't there yet.

But times, and cars, they are a changin'. Fast.

Here are four great reasons to make your next car electric.

1. It's step one to Planeteer initiation.

OK, so you probably won't actually get a ring that combines with other powers to summon a blue, muscly flying man whose sole purpose is saving the world.

The power is YOURS! GIF from "Captain Planet and the Planeteers."

But reducing fuel consumption is a major step toward limiting CO2 emissions, which means you're doing more to stop pollution from getting out of hand. And you know Captain Planet would totally make you an honorary planeteer for that.

Of course, all cars still require power to go. Even if you're not emitting carbon dioxide from your tailpipe, the electricity you use to charge an electric car releases some harmful greenhouse gases into the atmosphere. But the U.S. Department of Energy shows us that it's half the CO2 a gas-powered SUV would emit.

Not too shabby, eh?

2. Electric power is downright powerful.

You've probably heard of this guy Elon Musk, and his car company Tesla Motors. They've done what Toyota failed to do with the Prius and made the electric car straight-up sexy, and they made people want to buy them.

But they also made these things damn fast.

Grab onto what you can because the G forces from these cars will, without a doubt, send you flying. Check out the "insane mode" reaction videos on YouTube.

Fun fact: At 28 years old, Elon Musk made his first big break in Silicon Valley with the sale of PayPal, and he bought himself a McLaren F1. It was, at the time, the fastest car in the world, with a 0-60 mph acceleration time of just 3.2 seconds and a top speed of 240 mph.

With the Tesla Model S, Musk wanted to match the F1's 0-60 mph time, and when Tesla launched the P85D — a performance variant of the Model S sporting a 85 kWh battery— they did.

And now there's the Tesla P90D and its absurd Ludicrous mode, which can do the 0-60 mph sprint in 2.8 seconds. So, yes, an electric car is now faster than a supercar and can beat a Ferrari or a McLaren in a drag race.

3. Those tax breaks are phenomenal.

How does an extra $7,500 in your pocket sound? Come tax season, that's exactly what you'll have if you choose to go green with your car. There's a federal income tax credit of up to $7,500 if you buy a plug-in hybrid or electric car.

With some used models, that's enough to knock almost a quarter of the prices off the purchase amount. Add that to the amount you'll save in monthly gas costs, and with the right buy, your car could pay for itself within three to four years.

4. Your options are growing every year.

For the past 100 years or so, electric cars were about as popular as I was in middle school. There weren't often many choices on the market, much like my options for dates to the seventh grade formal.

But my, oh my, how times have changed! I'm getting married, and electric cars are the belle of the automotive ball. At the North American International Auto Show, Ford, Chrysler, Nissan, and Chevrolet all introduced electric or hybrid vehicles, while another new electric concept, the Faraday Future FFZero1, attracted crowds and press at the Consumer Electronics Show in Las Vegas.

Even the luxury manufacturers are getting in on this game. Porsche is launching their Mission E electric vehicle by 2020, with 700 million euros and 1,000 new jobs invested in the project. Lamborghini is creating the Asterion. Koenigsegg has created the Regera.

For the first time in nearly 100 years, the entire automotive industry is investing in the development of electric technology. Frankly, it's pretty freakin' awesome.

5. Maintaining electric cars is a breeze.

There's no engine. That means there's no oil to check, no pressure systems to get thrown out of whack, no fan belts that can come loose, no cylinders that need replacing, and no coolant that needs topping off. At long last, no more "check engine" light that won't turn off, even though you religiously bring your car in for its 5,000-mile checkups.

In Tesla's business model, when their cars need an update, they can simply send out a wireless software update. It's like you're driving a big phone on wheels, and most updates can happen overnight, while your car is charging and you're sleeping.

Tune-ups here and there will always be necessary, but they'll be fewer and farther between. Photo by Fred Dufour/Getty Images.

Of course, that doesn't mean that regular maintenance is a thing of the past. You still have tires that need air and rotating and axles that need proper care and attention. There's still paint and a body that needs protection and an interior that can be damaged.

But they're things that can be much more easily managed by someone who hasn't spent a lot of time hanging out around a body shop.

When you're looking for your next car, consider the one that'll keep the earth happy.

But also consider the one that'll keep you and your budget happy, in the short and long run.

There's little doubt around the world that humanity, as a whole, needs to move to sustainable technology. But without the votes of consumers, it is going to take a much longer time.

Whether we like them or not, cars aren't going anywhere. But the types of cars we choose for ourselves count as our loudest vote to one of the world's largest industries.

NASCAR is right up there with football and baseball when it comes to sports Americans love.

Professional stock car racing is fast, thrilling, and a serious moneymaker. In 2012, NASCAR earned $3 billion in sponsorship money, more than double that of the NFL.

Breakneck speed and passionate fans are the cornerstone of this wildly popular sport.


But! Here's an idea: What if those loud, gas-guzzling stock cars were replaced with electric cars?

Take it easy, Tony Stewart. It's just an idea.

Think I'm nutty for even suggesting it? Don't blame me. It's all Bill Nye's idea. In a January 2016 op-ed for Aeon, the TV science guy and beloved bow-tie wearer proposed that NASCAR cars make the switch from gas to electric engines.

Nye, a Southerner and lifelong stock car enthusiast, says he is disappointed by the lack of innovation in racing and suggests that, instead of clinging to outdated modes of technology, NASCAR should embrace the future and make the transition to electric cars.

"Despite the excitement, NASCAR kinda breaks my heart," Nye writes. "It’s a celebration of old tech." He wishes NASCAR was more like NASA, where the focus is always on the future and innovation.

"I wish NASCAR set up Grand Challenges to inspire companies and individuals to create novel automotive technologies in the way NASA does to create novel space technologies," he says. He even has a plan, a vision, for what NASCAR would look like with electric cars:

"It’s easy for me to imagine an electric race car that completely outperforms a gas-powered competitor. Instead of refueling a gas tank, the electric race car pit crew would change battery packs. The car would be designed to roll up a ramp. The battery pack would be disconnected and dropped out. Moments later, a fresh battery pack would be lifted into place, and off our electric racer would go with time in the pit comparable to what it takes to refuel and service a conventional gas-powered race car."

While this image sounds idealized, the real question is whether it's even feasible. Can electric cars even compete with their gas-powered counterparts?

Yes. Yes, they can.

Electric vehicles are already on track to compete with NASCAR.

NASCAR vehicles are built for speed. They have large, finely tuned engines that can take in huge amounts of air. They run without mufflers and catalytic converters so nothing slows down the exhaust. All the other systems on the car are built to operate at high speeds and temperatures.

All of these factors, along with a skilled driver, allow NASCAR vehicles to get anywhere from 800 to 940 horsepower and go from 0 to 60 miles per hour in about 2.9 seconds.

As Nye points out, the Tesla Model S, a luxury electric car, is capable of producing 530 horsepower and goes from 0 to 60 in 2.8 seconds.

It's not built to perform like a race car and weighs in about 1,000 pounds heavier than most stock cars, but initial tests make it clear that the Model S and other electric vehicles have potential for racing success.

While electric vehicles can compete with gas-powered vehicles, making the transition across NASCAR wouldn't be easy or affordable.

The speed and power required by the average NASCAR race car does not come cheap. One team, Joe Gibbs Racing, builds engines that cost around $80,000 a piece. One of those engines won't even get you through the nine-month NASCAR season. Not even close. Due to high speeds and punishing conditions, it only takes one or two races before serious engine maintenance or replacement is required.

Electric vehicles use motors powered by large batteries instead of fuel. While a fuel engine only lasts a couple of races, that's still better than the battery life of electric cars, which would need to have new battery packs installed during races because their range is 270 miles under traditional conditions.

While prices have fallen sharply since 2007, the cost of electric vehicle batteries is still between $300 and $450 per kilowatt hour. To be on par with gas-powered vehicles, researchers say that price would need to fall to around $150 per kWh, a milestone that's expected to be more than five years away.

For their part, NASCAR has taken a few major steps to offset the hefty emissions of their current cars. The 43 cars in the 2015 Daytona 500 used an estimated 5,375 gallons of gas. However, the cars use a biofuel blend made from corn that cuts emissions by 20%; since 2009, NASCAR has planted 370,000 trees, enough to offset their national series racing carbon emissions for the next 40 years.

Nye also predicts the influence NASCAR's adoption of electric cars would have on the consumer market and the economy.

While still years away from feasibility, a transition like this could give alternative vehicles and the sport of NASCAR racing a serious boost.

Imagine watching dozens of souped-up electric cars race around the track. Nye believes it would inspire fans to seriously consider electric cars for their own needs.

"The market for electric cars would go crazy. Manufacturers could not produce them fast enough," Nye estimates. "We could convert our transportation system to all-electric in less time than it took to go from horse-drawn to horseless carriage, 20 years maybe."

Though Nye is a font of optimism, he may have a point. Race fans are notoriously loyal and passionate. One market research firm reported 40% of fans are willing to switch brands to buy NASCAR-branded or sponsored products. This transition could be the boost EVs need.

NASCAR stopped releasing attendance data in 2012, but many signs point to declining numbers. And while it is still popular, TV ratings for televised races have dipped as well. Perhaps an innovative transition like this would inspire fans old and new to give the sport another look.

Critics will say Nye's plan for an EV NASCAR will never work. But imagine for a moment if it does.

Consider the innovation an idea like this begets, the emissions it could eliminate, the good habits it may inspire. Ambitious? Yes. Feasible? Maybe. Either way, the avenues for opportunity are enough to get anyone's motor running.

True
Natural Resources Defense Council

Cars are an expensive — but often necessary — part of life. And electric cars? Forget it.

That tends to be a problem with a lot of sustainable products: the overhead is just too high, even if it does ultimately pay for itself in the long run.

Unfortunately, this still leaves proponents of clean living in a a pickle. The only reason that fossil fuels seem more affordable is because of the infrastructure that's already in place.


How do you get people to make a large-scale shift toward greener transportation (which would bring prices down for everyone) when most of them don't have the cash for that initial investment?

The obvious answer is to just make them cheaper — and that's exactly what France is doing.

At the COP21 Climate Conference in December 2015, French Minister of Economy Ségolène Royal announced a global competition to create a small electric car that will sell for less than $7,500 (about 7,000 euros).

According to Gizmodo and speaking through a translator, Royal explained that her goal is to "create an electric car for the people" — something light, small, and fast-charging that "may not look like traditional electric cars."

To help keep costs down, the French government is encouraging the use of replaceable batteries (not unlike the innovative Gogoro Smart Scooter), which can be easily swapped out and replaced at designated charging stations throughout the country.

Presently, the next-best option in electric transportation (for those of us who can't afford a $45,000 Tesla) is India's e20, which costs around $15,000. The Renault ZOE is also available in France for around the same cost, plus 49 euros a month for battery rentals.

The ultimate goal, of course, is to incentivize the development of affordable, sustainable transportation all across the world.

"The problem arises for other countries: they worry that if we stop the exploitation of fossil fuels, it hinders development," Royal explained in an interview with 20 Minutes (roughly translated in-browser by Google).

"It is therefore imperative to drive down the price of renewable energy to provide these countries the same level of development as the industrialized countries that have reached the using in the past, fossil fuels."

There will inevitably be cynics who question the lack of specifics available thus far in France's cheap electric car plan. But what matters more right now is the country's willingness to take these kinds of risks.

And considering the tremendous strides that France has already made in sustainable development, there's no reason not to take them at their word.

The affordable electric car initiative was only one piece of a four-part plan that will double France's already considerable investments in clean energy.

That new plan also includes:

  • A commitment to bring the country to at least 20% electric vehicles by 2030 (part of the Paris Declaration on Electro-Mobility and Climate Change and the Zero Emission Vehicles Alliance). As noted in the official statement, “The higher volume of orders will help reduce production and marketing prices."
  • An additional 2-million-euro investment in MobiliseYourCity, which aims to facilitate transport planning projects in 20 cities in developing and emerging countries (and is only one part of an even larger global initiative).
  • Solar. Freakin'. Roadways! (OK not exactly this, but close enough.) Over the next five years, the government plans to deploy at least 1,000 kilometers of "energy roads" that incorporate photovoltaic cells to generate electricity.

Clean and affordable transportation is just one step toward a brighter future. But it still makes a difference.

Like I said, the only reason that fossil fuels are cheaper is simply because that's the infrastructure that's already in place. But if that same infrastructure had been established with a renewable, non-carbon-based fuel source, it would cost us even less — without the added bonus of environmental damage.

But because of that infrastructure that's currently in place, the only way to enact wide-scale change is to go all-in and make it happen — and that's exactly what France is doing.

Together, we can create a new global infrastructure that works for the people and the planet, instead of just the pockets of a few corporations.
