In Finland you're allowed to park mopeds where ever you're allowed to park bikes aswell (as long as it's outdoors)
When I was 15 and had my 50cc scooter I remember the 5 litre gasoline tank lasting me about a week. Yeah it's still burning fossil fuels but at that rate the emissions are quite insignificant. Being 4-stroke it was quiet too and didn't make my clothes smell like exhaust fumes.
