Cars are looking very good from what I have seen so far.
Parking spots all around the world, drive the car with WASD, control things like lights, the roof etc. And yes, realistic traffic (which can probably be configured in the settings). And if you don't want that you can skip the ride or use local transport. I think there will also be scooters and bicycles from what I have seen in videos but they are not usable yet.
Now we actually have to take the time to travel into account when playing, the sims 4 just lets us teleport to work instantly which while it's convenient... is really unrealistic.
The cities are small compared to Night City in Cyberpunk 2077 and Stilwater in Saints Row 2 so I will probably prefer to walk or use the public transport.
