They've been hinting at cars for awhile so they might be coming. Also I would love more gameplay with cars since I'd expect cars to work like they do in Sims 2. Like washing inside and outside. Have Jobs like Delivering and Uber, Have like a licence and teaching teens or maybe all lifestages after teen as well on how to drive like they study the permit and depending on how much they learn the pass the test.
I really hope they would add something like what you're describing! I think it's cute that adult Sims can teach children how to ride a bike, and it would be awesome if there were something similar (but preferably a bit more interactive) with cars/driving. They could add driver's ed as a high school class and allow teens to practice driving with their parents. It would also allow EA to add some funny milestones like "accidentally bumped into another car for the first time" 😆
