He LOVES driving the car. When we get home from driving around he crawls out of his carseat and climbs into the front seat and starts turning knobs, steering the wheel, honking the horn (only rarely does he succeed), turning on the wipers, etc. When I got back in the car after the first time he played in there, the heat was on full blast at my feet and the wipers were on.
I've been buying toys and books and hiding them for our first flight back to the Bay Area. So far I've got little trucks, books about trucks, and a Doodlepro. If anyone has any other ideas, let me know. Of course I'll have an arsenal of snacks, but this kiddo has a short attention span and likes to move not be confined to his carseat.
