Can you really drive on those at high speeds, is it dangerous?
There's a few short blocks in NYC that are still cobblestone and even at 30mph it sucks.
It's ridiculous when there is a wide, flat, straight asphalt road surface with a speed limit of 25mph. Build it out of cobblestones, and 25mph suddenly feels a lot faster!
But how would cyclists fare on cobblestones, especially if you were talking about suburban streets with kids playing, bikes going around, etc?
Really painful and annoying to ride on with a kick scooter though.
