I find these discussions seem to be dominated by young urbanites. People who don’t need a car to get around as opposed to the huge number of people who live in areas that require a car to function. They are also physically able to bike many miles every day in any weather.

I took public transportation when I lived in a big city and was glad to have it but anytime I needed to go beyond a limited area in the city I needed a car. Now I live in an area with very limited public transportation and very very little is in walking distance and biking for my needs is not an alternative. Frequently using 100% public transportation routes would increase your travel time by a large amount, time you may not have or want to sacrifice. If you live in country like France it seems like the transit unions have a stranglehold on the nation as they can shut down everyone at will, if you have a car you at least have an alternative. There are also breakdown issues, maintenance shutdowns, etc. You also run into the last mile issue a lot. Where you need to go is frequently not a reasonable distance from the stop. I usually needed a car to get to the train stations for instance.

Because to them, ‘car’ and ‘vehicle’ mean the same thing.

Autonomous vehicles work better on rails. Also without having to deal with pedestrians.
