Once the number of cars is reduced significantly, it will be much easier and cheaper to have really good public transport, since there aren't so many cars on the road any more. And we save costs due to less road maintenance (which is really expensive), no need to build new bridges/roads to solve traffic jams, lower health care costs, less time spent (i.e. money wasted) sitting in traffic jams, lower environmental costs, and you can put that in public infrastructure. I think it's good to be mindful of these kind of issues: for all their downsides, cars can give great personal freedom and I think it's good to think how that can be maintained, but it's not like cars are the only way these problems can be solved.
