The one thing I noticed in NA is that it takes ages to rebuild a road. I have close to zero experience in road construction, but a bit weird to see how they can repave a km stretch of a road here in Tokyo within a week or two, but it took months in other cities i've lived in. Maybe they do a lot of extra work over night over here in Tokyo, and it just goes faster? Or it's a very systematic thing and part of the maintenance schedules, so it doesn't really go that bad?
