@Efi Well for one thing, each floor on buildings would be taller! And doors quite possibly wider. With much higher doorknobs.
Revolving doors? Right out.
I doubt public transport would be needed: centaurs are quite mobile on their own! Not sure how inter-city transport would best operate.
Vehicles are interesting to contemplate. They wouldn't have seats, probably; just room to stand, wheel and shifting mechanism high enough for comfort, and probably a pedaling system much like human cars.
Not gonna touch those other issues though ∑;p
@Efi Yeah, for long range transit, I'm imagining trains might be the preferred vehicle.
They've got hauling power. That means they can pull *big* cars with lots of room for centaur-splay.
Probably ample supplies of hay, too. Bedding and bonus free snack! 😹
@Qwyrdo they would definitely think of some way to get extra comfy on long rides, no way anybody would be hours standing on a bus, that's awful even for a horse
they like to lay down too, y'know?
