I’m not sure what you’re agreeing with here. I didn’t say anything about roll curbs; my point is just that if right turns aren’t permitted, the curb can come to a sharp corner instead of being rounded off to provide a turn radius. A roll curb that comes to a sharp corner is dangerous because it makes it look to pedestrians like they have a safe space right at the corner but provides not even a hint to a vehicle that it has transgressed into pedestrian space.
