Of course cars have a place too. Having two smallish children, cars are a great way for my family to get around for many things. But it's nice when they are one option among many, and not set on a pedestal as the only one.
For instance, when we lived in Padova: we'd ride bikes around the neighborhood when the weather was good. I'd walk to get groceries. My wife and I often rode bikes downtown for 'date night'. We'd take the car to do larger shopping trips on occasion, or to do things further from town. We'd take the family downtown on public transportation. So it was a 'right tool for the job' situation.
I don't think we really need any fancy, expensive technical solutions like burying cars in tunnels - just making streets a bit slower, and safer for bikes and pedestrians would be a great start.
