Someones always gotta different. In order to really get a driving game with real life type physics would make the cost of the game extremely high because engineers would actually have to work on the fluid dynamics, system dynamics, strength analysis and a lot more factors. Some people expect real life but don't have a clue as to how difficult that is to model.
Hell, real life physics isn't even perfection, it's just close enough values compared to real life.
