It's worth noting that public transportation exists, not just bikes and cars. Designing city less oriented around cars would mean that you could take your kids to the doctor on a train/bus/walk, and that your grocery store wouldn't be 15mi away, and not need to buy a week's worth of groceries at a time.

Of course you could choose to drive anyway, but as long as people have the option to rely less on their cars it's a net win.
