"Need" is doing a lot of heavy lifting here. I live in London, UK. We have lots of public transport. About half of my journeys can be done via public transport, about half of them can't. By can't, I mean that they are significantly slower, would require taxis on one or both ends, or simply are not possible due to one end being semi rural or rural. The half that can't represent far more mileage, emissions, etc. They also frankly are most if not all of the fun ones. Public transport works if you live a solely metropolitan life. If you do anything else, it just doesn't scale at all. This is of course ignoring the fact that in my own car I don't have to experience feral beings.
