Lack of large domesticated animals is also a fairly big factor. A big cart or wagon is great when you have creatures like horses or bulls, combined with staircases and terrain though? No big reason to make them

1. Motorcycles are much more dangerous than a car or trike and generally require a specific type of license to operate, making them a bad solution.

2. It's a pizza delivery, why the fuck would they need to transport more than 1 person. You're not going to be carpooling in these things, they're not taxis, there's legitimately no reason to require 2 seats.

Like, I get not liking companys and the like, but your arguments are just nonsense.
