The average American spends nearly an hour a day behind the wheel, according to the US Department of Transportation. Some people love driving. Others tolerate it in order to get around. But either way, on average we all spend a lot of time doing it.
So it’s understandable if, over time, we all come to believe a few things about our cars that aren’t true. There’s nothing more human than believing myths, but some of these false beliefs have people wasting money or getting upset at people who are actually doing the right thing. With that in mind, here are a few widely believed driving myths—and why research suggests they’re false.
Diesel aside, there are three kinds of fuel at most gas pumps—regular, plus, and premium. The overwhelming majority of personal vehicles are built with regular fuel in mind; it’s basically just sports cars and a few luxury vehicles that require the higher octane.
Some people believe using premium fuel offers benefits, such as higher fuel economy, increased performance, or reduced tailpipe emissions. But there’s no evidence to support this idea. Engines are designed with a specific octane in mind. Using a higher octane won’t hurt anything, but it doesn’t benefit the vehicle in any way.
A 2016 study by the American Automobile Association (AAA) tested different fuels in identical cars. The study found no consistent increase in horsepower or fuel economy, and there was also no change in tailpipe emissions. The only real difference was the price of the fuel.
A 2003 publication from the US Federal Trade Commission put it plainly: “In most cases, using a higher octane gasoline than your owner’s manual recommends offers absolutely no benefit.”
Generally, if your car requires a higher octane fuel, there will be a sticker saying so when you flip open the fuel door. If not, check your car’s manual—it will state which kind of gas your car needs. But basically, if you don’t own a sports car or luxury vehicle, you should just use regular fuel.
There’s a widespread belief that, if there’s a lane closure up ahead, people should merge into the open lane as soon as possible. The problem is that doing this slows down traffic. “When most drivers see the first ‘lane closed ahead’ sign in a work zone, they slow too quickly and move to the lane that will continue through the construction area,” reported the Minnesota Department of Transportation. “This behavior can lead to unexpected and dangerous lane switching, serious crashes, and road rage.”
There’s research backing this up. A 1999 study by researchers from the University of Nebraska showed that traffic moves faster if people stay in their lanes until the merge point, then take turns merging. A 2018 study from North Carolina State University shows that there’s a real safety benefit to this system, which is referred to as a zipper merge. According to the study, “drivers merged at much safer distances after installation of the zipper merge at these sites than before the zipper merge was in place.” The study also found that the zipper merge was safer for construction workers. A 2024 paper by researchers from Iowa State University analyzed construction sites in Michigan and Missouri, where portable lit signs instructed drivers to stay in the closing lane until the merge point. They found increased traffic throughput at those sites.
The problem is that not many people know about the benefits of the zipper merge. Some drivers get angry at drivers who don’t merge early, and in some cases will even cut them off. But research suggests everyone would get home faster if we all stayed in our lanes until the merge point.
This myth was true, at some point, and still might be true for particular cars with particularly skilled drivers. Overall, though, there’s no real fuel economy advantage to driving a modern manual car. That’s according to the US Department of Energy (DoE), which stated that “advances in automatic transmissions have improved their efficiency to the point that the automatic version of a vehicle often gets the same or better fuel economy than the version with a manual transmission.”
Anyone who is interested can head to FuelEconomy.gov, a website run by the US Environmental Protection Agency (EPA) and the DoE. On this site you can see the miles per gallon (MPG) for any make and model, allowing you to directly compare the manual and automatic versions of any car. You can dig into the numbers yourself, comparing the automatic and manual version of the same car—assuming, that is, that the car is available as a manual. Such vehicles are a relative rarity in the United States, possibly making this myth largely academic (and that’s before we factor in the shift toward electric cars).
The post 3 driving myths too many people believe appeared first on Popular Science.
There are over 283 million cars cruising the United States, and over 90 percent of them are still guzzling gas. Apart from the obvious environmental problems, fuel prices also continue to skyrocket thanks to the ongoing war in Iran. The average price for gas is currently around 33 percent higher than it was before the crisis, and there is little sign that those numbers are going down anytime soon.
The strain is forcing many drives to reconsider how they get around—and they’re getting creative with it. In Georgia, a 30-year-old handyman is showing everyone how to properly adapt to uncertain times. According to a recent Reuters profile, Mali Hightower has retrofitted a discarded, bright pink Power Wheels Barbie Dream Camper with a two-gallon, one-piston engine for his shorter commuting needs.
“I drive this when I can,” Hightower said on May 19.
To get it going, a driver simply pulls the rip cord that’s attached to the former power washer engine. At less than four-feet-tall, the Dream Camper may not be the most comfortable ride for a full-grown adult,but it’s definitely cheaper. Hightower likely still prefers driving his 1996 Mercedes-Benz convertible, but with a full tank costing him around $90 right now, he’s more than willing to use his Power Wheels alternative for errands like grocery runs.
While somewhat surreal to see at a gas pump, the DIY solution underscores a more important issue: the need for more people to divest from fossil fuel rides in favor of public transportation and electric vehicles (EVs). Unfortunately, that’s easier said than done for many people. The U.S. is dramatically underfunded when it comes to options like commuter bus routes and trains, while EVs are still out of many people’s price ranges. The Dream Barbie Camper may be one-of-a-kind right now, but there’s a good chance that similar, intentionally constructed alternatives are on the way. At least those will be able to comfortably fit the driver.

We’ve seen Waymo’s fleet of autonomous taxis cause plenty of mayhem on public streets. They like to ignore bike lanes, drive the wrong way down busy roads, and even rely on remote workers in the Philippines when they get stumped.
Riding them can also quickly turn into a terrifying near-death experience, as one couple in San Francisco found out firsthand. As CBS News reports, the couple was looking to get home in the Mission District only for their Waymo cab to veer off a highway and accelerate to terrifying speeds while driving down a construction lane.
All the while, police vehicles were trying to chase it down with sirens blaring.
“There were construction signs,” resident Elliot Slade told the broadcaster over the weekend. “There were lights going on. Police in the distance and it sped up. That’s when I looked at my fiancée, we’re done.”
“This is it,” he added. “We’re dead. We’re going to die right here in the Waymo.”
The terrifying incident underlines the very real dangers of relying on autonomous vehicles for ride shares, while they still suffer from nagging technical shortcomings that are putting people in danger. It could also further erode public trust in the tech.
In the last two months alone, Waymo’s vehicles have been observed driving through flooded streets and speeding through construction zones, as USA Today reports.
The latest incident also proved scary enough for Waymo to pull its cars from freeways in San Francisco, Los Angeles, Phoenix, and Miami altogether as it works to “integrate recent technical learnings into our software,” according to a statement to CBS.
The offending Waymo vehicle “started freaking out,” Slade recalled, because of a slew of merging lanes, causing cars to be “all over the place.” Smartphone footage Slade recorded shows the dramatic incident from his perspective.
“Holy s***, dude,” Slade can be heard saying in the clip.
After speeding up for around 20 seconds, the Waymo eventually pulled over, with a representative chiming in over the car’s audio system. Understandably, Slade and his partner were desperate to leave and never look back.
“She came on the line and said from what I could see, it seemed like a stressful experience,” Slade told CBS. “What do you want to do next? I was like we want to get out. They’re like do you want to continue the journey; I was like absolutely not.”
Waymo offered the rattled occupant $40 worth of free rides, but understandably, he’s now unsure about climbing back into one of its vehicles.
“It was one of those things, once you lost your autonomy in the car, I don’t want to feel that again,” Slade told CBS. “Like it was a really freaky moment.”
Meanwhile, a spokesperson told the broadcaster that the company expects to resume its freeway routes “soon.”

It turns out not even the people building Tesla’s self-driving tech trust Elon Musk’s extravagant claims about the company’s autonomous vehicles.
New reporting by Reuters interviewed nine former data labelers and a former self-driving engineer about their take on Tesla’s Full Self-Driving mode. The results were overwhelmingly negative, with seven of the data specialists admitting they wouldn’t ride in a Tesla in FSD.
“We have all seen it fail,” one Tesla insider told Reuters. “Definitely don’t trust Elon on this,” the self-driving engineer concurred, referencing Musks’ declaration that the the vehicles are ready for “safe unsupervised” rides.
One erstwhile worker told the publication they wouldn’t ride in a Tesla robotaxi “if you f**king paid me.”
At least five data labelers, whose job was to comb through hours of FSD footage to train the vehicle’s software to avoid past mistakes, told Reuters they routinely saw clips of Teslas driving above the speed limit, an issue which engineers and managers treated like a low-priority compared to edge-case issues.
Those glowing recommendations come amidst concerns that Tesla’s FSD mode may never be truly safe enough for public roads.
In recent months, Tesla operating on FSD move have driven riders into lakes, off bridges, and even into the path of oncoming trains — and those are just the incidents that get media exposure. Given these insiders’ direct access to terabytes’ worth of proprietary FSD footage, we’re inclined to take their word on it.
More on Tesla: Man Drives Cybertruck Into Lake to Test Elon Musk’s “Boat” Claims, and It Went About as Well as You’d Guess

Longtime Cybertruck watchers might remember a peculiar day back before the brutalist pickup was even released, when Tesla CEO Elon Musk randomly tweeted that the vehicle would function as a rudimentary flotation device.
“It will even float for a while,” he wrote at the time.
It wasn’t a one-off claim. Musk later boasted that the vehicle would be able to “traverse at least 100m [330 feet] of water as a boat.”
“Mostly just need to upgrade cabin door seals,” he claimed, writing at another point that the “Cybertruck will be waterproof enough to serve briefly as a boat, so it can cross rivers, lakes and even seas that aren’t too choppy.”
The Cybertruck finally did make it to market, where it’s suffered a seemingly endless parade of recalls, embarrassing incidents, and dismal sales figures.
Unsurprisingly, all Musk’s bluster about the truck serving as a makeshift schooner turned out to be flimflam. In fact, it quickly emerged that just getting wet in a car wash could brick the thing.
To muddy the waters further, the company ended up adding what it calls “Wade Mode” to the vehicles, which sets the truck’s ride height to the highest level, ostensibly so it can ford creeks and streams.
All that mixed messaging clearly got jumbled for a Texas man, though, who activated Wade Mode and drove his Cybertruck into a lake. Unsurprisingly, things didn’t go well for him.
“Yesterday, [Grapevine Police Department] and [Grapevine Fire Department] were dispatched to Grapevine Lake, where a Tesla Cybertruck was stranded in the water,” police in Grapevine, Texas, wrote on X-formerly-Twitter. “The driver drove into the lake to use the ‘Wade Mode’ feature when the vehicle became disabled.”
Not only is the man’s vehicle swamped — as the cops showed in an amazing attached photo — but he’s in legal trouble as well.
“The passengers abandoned the vehicle and the driver was arrested,” they wrote.

The world’s biggest miner has halted or delayed projects to cut vast amounts of emissions and has quietly war-gamed options to push major climate investments in its Western Australian iron ore operations into the next two decades, internal documents show.
An exclusive investigation based on documents leaked to the Guardian and the ABC’s Four Corners can reveal that BHP, one of Australia’s biggest historic emitters, has dumped plans for a facility that could have significantly reduced emissions and has put on ice renewable projects designed to power its iron ore operations in the vast, resource-rich Pilbara region.
