Between cars, trucks, mopeds, bikes, and scooters, I think it would take forever to list all of my peeves when it comes to traffic here.
But... one that has bothered me lately is construction workers who insist on parking on the sidewalks near my building. The road is mostly closed to traffic while they're working (including no through traffic at all), and there's plenty of room for them to park at the curb. So why do they have to block the sidewalks, which are already less than perfect?
