Also because cars create a huge number of negative externalities that impose additional costs on society as a whole. Pollution, climate damage, accidents, wear and tear on roads and other infrastructure, increased public transit costs because transit has to contend with traffic, etc. As someone who does drive, I absolutely should be made to pay for those costs.

Singapore has one of the best transit systems in the world, and owning a car is so expensive that it's more of a status symbol than anything.
