This as a pretty awesome list, I'm gonna save it.
One thing you could add is e-bikes, depending on how good the bike infrastructure is where you live. We were able to completely eliminate a second car because I can bike much further to work without getting sweaty. 9 miles each way. Also bike to some other local things like farmers market. Unfortunately my dad got old and we got a hybrid for free since he can no longer drive, to help him with appointments. But it was working in concept until that point.
