Even in places where public transportation is very good, no bus goes everywhere or all the time, and trains are still limited to very specific routes. Need to go to the supermarket to buy food for your whole family? Not very practical on a bus. Live in rough area and come home from work late at night? Perhaps a car is safer. And so on. And this is in a city, it's even worse in rural areas.

Even as someone that loves electric vehicles and uses public transportation a lot, it's hard to get behind these extreme "let's ban X and go all on Y" views. It ignores how things work in the real world.
