Not having cars in the game have bothered me since day 1 when the game was released.
Without it neighborhoods and lots feel like movie sets, the solution of having sims fading away into nothing have always looked bad in my opinion or when sims like firemen appear out of thin air.
It doesn't feel like you are traveling anywhere and it also makes it unnecessary complicated if you want to build lots with garages or parking lots. There are plenty of cars driving around in the neighborhoods but we can't own one ourselves?
