Probably true, but all of those are significantly more involved installations or modifications.

To be clear, I'm all in favor of reworking neighborhood roads to be more friendly to pedestrians, but I think things like signs have a significantly better chance of actually being implemented in most circumstances.

Of course, drivers respond to speed bumps the same way they respond to other poor road surfaces: 3-ton SUVs.

They put one in front of my friend's house. It's a big plastic one almost as big as a speed table. The complainer Karens drive .03mph over it and get honked at or driven around. The trucks and vans, anything driven by an employee or a teenager just speeds right over and a small number of people go for air time. 11/10. Highly entertaining. And this is all in addition to having to listen to every vehicle accelerate after it of course.

Good synergy with those "road-diet" narrow chokepoints then.
