People have been told by the Public Works Department that speed tables work, that differences have been measured on, for example, Camino Lejo after the installation of speed tables. Never mind the fact that Camino Lejo residents regret the installation and wish the devices were gone, people want speeds to slow and they believe in the solution.

It’s possible that there’s a measurable decrease in speed
after the installation of speed tables, but only when considering the averages.
The reason? People who strictly obey the speed limit and people with extra low-ground
clearance cars will slow down to about five mph directly in front of each speed

have figured out that, while old-fashioned speed bumps are pretty nasty unless
