We have a 2-car garage and both cars fit side-by-side. We both prefer driving the smaller car, so that gets the majority of the usage. We used to have a singe car, but since I took a job too far away to bike to, we had to get a second car.

So for me, I think it's weird to have cars specific to an individual, I have always seen cars as a tool that you use when you need it, and you pick the best tool for the current job. I would love to drop back down to a single car, but I'm not ready to leave my job yet.
