Having a car free city center sounds like a good idea. It's not a car free city though (that sounds horrible, not to mention impossible). A city needs less dense areas and at some point outside the city center density will be low enough to a) not have public transit at the required frequency and b) be home for the type of places you need a car for (Lumberyard, car wash, ...).
