Probably fake, but if it's true, people don't know what they don't know.

To a whole lot of people mechanical devices border on magic. The gas goes in the hole, you push on the pedal and the car moves. That's literally all they know. They don't have any idea how an internal combustion engine works, much less an electric motor. They've spent their time learning things that are more important to them.

I'd hazard a guess that, apart from Bill Gates, the top billionaires are clueless regarding this stuff.

Hell, many race car drivers don't know much about it, they just know how the car feels.

If you know the four-stroke engine cycle--intake, compression, ignition, exhaust--, you're way ahead of 95% of people. Add to that how a camshaft controls valve timing and you might as well be a mechanical genius.

When you drive in reverse, smoke goes back in.

OP confusing cars and jets.

jets are the fart-powered vehicle.

And a bike is driven by the air your legs push back, the wheels are only there to slow you down otherwise you'd accelerate infinitely.

So 99% sure this is fake and never happened, but I've seen a lot of these "I'm really stupid" posts on 4chan. I imagine anon just wants to be part of a joke, even if they're the one being laughed at.

This is how I felt when I was explaining to the dealership mechanic about how my car would buck when shifting up after dropping into a lower gear to pass someone.

I called the lower gear the passing gear, and he looked at me like I was a moron.

I was vindicated the other day because my coworker from a family of mechanics (and being one in his free time) used it.

Born to be a pilot. Cursed to be a 4chan poster.

Technically the car is powered by the movement of the exhaust fumes... Just not in the way that OOP thinks, I would presume

That's to limit your speed in reverse, don't want to go 60 mph backwards

I mean, look at his head. He got dropped so hard I'm surprised he can type!

Pretty sure Olympic runners are just very good at farting 🤨

we all laughing but bro would write the best childrens books

This has got wind turbines for global warming vibes

Ahh, it's lovely to be driving a bicycle
