In a city, open space is scarce, so unnecessarily large vehicles make everyone else's life worse. They are also more dangerous to everyone who isn't inside the car. So the car owner is choosing to give themselves luxury while endangering others in order to do that. They also add more to the wear and tear of public roads, which costs the taxpayer, not them. It is therefore seen as a highly selfish trade that they've willingly decided to make without the permission of those who they are indirectly harming, and they do this in many cases for no good reason pertaining to their business or family size.
