Every time someone says "we should forbid cars in cities", I hear "we should take away 1 hour a day from your family, you should sit in bus instead". (or more likely stand, since the bus is always full)
I'm not fan of that.
I still take public transport. In a car I need to be focused for the full 45 minutes and be stuck in traffic, having nothing to do. In the train I can put my laptop on the table and work for 35 minutes straight before I need to switch to the subway. I can also recline the seat and take a 35 minute nap instead. It's amazing and really adds to my quality of life.
Presumably your commute is so much longer on public transport because neither your home nor your job is in the city center and there are fewer lines out there? Not saying that you deserve to suffer if that's the case, but also probably people aren't coming for cars in your neighborhood first.
