I don't fault you or anyone who has decided it makes sense to own a car on an individual level, but I still think the city at large would be better off without them. You could, for example, ditch your expensive parking garage for an electric bicycle, which you'd be able to ride safely if most streets were free (or mostly free) of cars. I could see an argument for allowing cars during certain hours late at night—but I don't think that would satisfy most drivers, and I think it would be tricky to enforce—if there's a mishap and you can't reach your destination on time, do you get ticketed? And, if we close only the most crowded streets, whichever streets in the area remain open will become crowded quite quickly!
