It would be cool to have a driving skill, I don't want my Sims to be able to just buy a car and drive it. That isn't realistic and it would be a cool ability for Sims to earn.
The lack of open world could make it harder for a car or driving skill but there could be ways to level it up
- Reading/researching information on cars and driving safely
- Taking your car apart, inspecting the pieces, and putting it together again
- Having your Sim's driving instructor coming to pick them up for a one hour driving lesson (even if the player doesn't go with them). They could give 'homework' to their pupils and be disappointed if lessons are skipped, maybe the driving instructors could be the ones who decide if your Sim has done enough to earn their driver's licence.
- "Practice driving around the current world" where your Sim goes off driving for a practice alone (going further than where the player can see them but returning occasionally to drive past their house - maybe they could sometimes beep their horn to their family/roomates as they pass). If they haven't earned their licence yet maybe they could only be allowed to do this with an experienced driver with the mentor trait.
