There's multiple kinds of complexity. Mechanically, an ICE is more complex. But materially, its arguably less complex, since it doesn't rely on rare earths or lithium, and the knowledge base for const...

"It doesn't rely on rare earths"
It relies on petrochemicals of which there are limited amounts, and certainly the amount you can burn is very limited if you don't want big environmental problems later.

There are solutions. Hydrogen fuel cells have great energy density, although operating needs care. Better for buses, trucks and taxis where the driver can be properly trained to deal with the dangers of leaks.

You can use sodium batteries which are extremely cheap, extremely safe, operate in environments you can't use petrol in let alone lithium. The only drawback is they have about half the energy density of lithium batteries. But for something so cheap who cares if you can only get half the range? Plenty of people will buy that

Sodium batteries are not cheap yet. There's so much untapped hydrocarbons that we aren't going to run out if we're smart and use them to make cheap electricitybuipd build next gen nuclear. Buuuuut... That doesn't match up with the commie green agenda.

I don’t have strong opinions on hydrogen but I heard it’s hard to contain leaks and that’s bad news because it’s a greenhouse gas. Perhaps it makes more sense on big ass haulers and not inside drunken driving teenagers’ cars.

I agree. Current stuff uses rare earths, and it shouldn't.

"Half the range" is simply untrue. You need to expend energy to transport your energy, range has a negative exponent.

small hydrogen gas engines properly made are quite safe. the flashback arrestor is critical. hydrogen produces 5-7 times as much impulse in the detonation and so the engine has to be designed better for thermal dissipation and higher RPMs but unlike carbon fuels it's output is water. fuel cells are...
