Seeing the monsters people call "cars" here, I am not sure I would feel safe having them behind me even on a 30 km/h street. It's one moment of inattention or malice for them, death for me.
Interesting article though:
I rode on that street yesterday, it's short and quiet. Hopefully, it's the way of the future. I'd rather have cars and trucks coming from behind at 30 km/h than 50/60 km/h as happens on every other street in town!
@Digger_71 - that's for sure, thanks!
