What about electric cars with nuclear power or renewables? In any case the argument is not about that. It's one thing to say "we cannot sustain the CO2 emissions / we cannot build enough highways for everyone so sorry, we cannot have some of the nice things anymore", but that's not what the above says.
It is also ok to express an opinion that car-free living is better for some people, or argue that most people prefer it, although I think that is self-evidently incorrect, cause as per IMF data I linked somewhere here, one of the first things people all over the world do when they get any richer (like, $2.5k-10k per capita income) is buy a lot of cars.
But the above is saying it's OBJECTIVELY better. Other than just being wrong, that betrays the kind of "I know exactly how everyone should live their lives, and I would make them if I could" attitude that I hate.
