i would probably prefer there to be buses. and trains from ecological and urbanism standpoint. but if i could id have a cool small minivan so me and my friends/polycule could go on road trips. or a motorcycle. i live motorcycles. but they're dangerous so i probably will never drive a one in my life.

cozy and comfy inside, exterior that is somewhat flat and easy to put loads of stickers on, maybe some nice pastel yellow and orange and green colors, could probably keep a little garden in there somewhere while still having room for other stuff and seats and it not looking weird

Hmm... I find a lot of vehicles pretty meh but, a 2014 hyundai elantra is probably the most comfortable car i've ever sat in. There small, and I like that, the seats are really comfortable (The one my mother owned had like-- Gamer chair styled seats.), there pretty fast (I don't really care about that part) but idk, small and comfortable, thats all I gotta say
