We still don't have any form of vehicular transportation!
In The Sims 4 we have a closed world. To get to a lot, you have to wait for a loading screen. This isn't any different from previous iterations, except The Sims 3 with its open world. I was bummed out...
I still think cars are possible by having them teleport to other locations plus make it to where sims can do interactions in them like they could in TS2 and TS3 with the fixable car.
