I, don't think that's how it works in Europe. From my understanding they love cars but they hate traffics, and they likely have bans for diesel (because diesel is not taxed the same way as gasoline) from entering urban center due to NIMBY first, then the traffic jams and parking nightmares. There were talks about cars entering urban center must be geo fenced into EV mode floating around in the past, and we know hybrid is already feasible without subsidies in 2021 so it should be very mature by 2030, like fuel injector is super reliable and nobody complains about carb going obsolete in 2021.
Yes you still need cars for the small towns and rural but not as much in the urban area. Remember their cities have way better public transit than US outside of maybe NYC, Seattles, and maybe San Francisco, etc.
Oh, they don't have oil and they have to import them, send military oversea to protect their energy security, etc etc. So they don't get the cheap $3 / gal gas we have in the US, try doubling them.
2050 is A LONG WAY FROM NOW. That's 29 years. What have we said about cars from 29 years ago? Did we ever envision mandating rear view camera? ABS? crash test we have today? or what about things that everyone entitle to like air conditioning, automatic transmission, 35mpg cars? fuel injection? regenerative braking? or things that last 250k miles without any major work? or those EV torque monsters? or all those good stuff we have now? Don't worry about 2050, something will work out by then and if not politics will always work itself out.
