I guess its wonderful if you like killing people. Reducing visibility around corners is unsafe in the US, far too many people will drive the same and just take a chance that its all clear, I know of a couple people who died that way.

I’ve seen this sort of thing work in London, so my theory is that traffic calming only works if you don’t treat vehicular manslaughter as akin to petty theft or even less as we do in the US. Good luck changing that, way too many people operate a vehicle everyday for them to want to take on that liability. Also young men are going to continue to drive with a devil may care attitude. Traffic calming measures in a motorist society like the US, in my observation, ironically cause much more aggressiveness on the road, and to me are the transportation equivalent of hostile architecture.

When done well, yes, it calms traffic. But random trees or bushes at an intersection on an otherwise wide open road isn’t a good idea.

They aren't calming when I can't see shit when pulling out into an intersection and turning.
