Realm of Magic's world Glimmer Brook also had homes with driveways which set off another round of speculation that cars were going to be a thing soon. But that happened a few years ago and cars still aren't in Sims4. With all the loading screens in Sims4 I just don't see the need for cars at all. In Sims3 with the open world, having cars and other vehicles made sense and added something unique to the game. I was especially fond of the motorcycles. I'm not anti-cars, I just think there are other features that deserve consideration first that will add some fun to the game and appeal to a larger portion of the players. Whatever that might be will remain a mystery until we get an information 'leak' or EA announces the theme of the next pack.
