actually in europe delivery service is done on mopeds or scooters.
The brown UPS truck is a brown UPS scooter with a box on the back.
The Dominoes pizza car is a dominoes pizza scooter with a hot box.
I saw hundreds of regular UPS trucks, just like here.
I also saw a lot of courier services and oriental delivery places using the Smart. It's probably not a good idea to pack the won ton soup or that architectural drawing on the back of a scooter.
Pizza Hut used a scooter though.
