In the summer bike is nice alternative, but during bad weather there's nothing comparable to the comfort of car.

Please remember not everyone lives in bay area with long commute and mild weather :-)

A 15min commute as you have is a different situation (much better!). Nobody is trying to take away your car. I realize that it is often framed that way in US media, as if the options are public transport OR private cars. I have a car in the Netherlands which I use for some trips where public transport is not the better choice. But when possible, especially when going from one major city to another, public transport is such a nice luxury. (It also means I can go have fun at that late night party and never face the decision of whether to drive somewhat inebriated or not.)

But yes, if we try to complement them, not just ban, this is very reasonable. I also travel by train quite often because it's simply very convenient compared to car.
