I'm an American software developer who lives near the headquarters of Microsoft. My car is 15 years old. Cars just last a hell of a lot longer than they used to. Even if every Western manufacturer stopped making petrol cars, you could still buy them from Russia or China. And everyone stopped making cars, well, it's not impossible to have a domestic auto industry. After all, Detroit started from nothing. If you didn't care at all about emissions or fuel economy, a large-displacement 2-stroke engine wouldn't be hard to make. Heck, in the future, it might be harder to get hydrocarbon fuels (either synthetic or ultradeep drilling, which really does require exotic technologies) than it would be to make engines.
