Driving in a city with even a basic public transit system is almost always slower than taking the train anyway, so time isn't really a factor. As for comfort, I don't think all the negative externalities of having a car-centric urban area are worth that trade off - what about the comfort of bikers and pedestrians that cars disrupt?
In the US at least, we already massively subsidize road infrastructure and gasoline, I think it's fair to let people who actually live in cities enjoy them, rather than bend over backwards to accommodate suburbanites who only come in for work.
Also, cars aren't a magic ticket to mobility. Elderly people often can't drive and end up stuck in their homes. They have to be purchased or leased, and maintained, etc.
