How do you slow people
down without disrupting the travel of those obeying the speed limit? You create speed bumps that pop up only when someone is speeding.
Speed bumps do a good job of penalizing non-speeders as much as speeders, and they typically force drivers to travel well below the speed limit. With that in mind, inventor Gwyn Harvey came up with a radar-activated speed bump design that would only deploy to slow drivers traveling at an unreasonable speed.
Sounds like just the thing for many neighborhoods. Of course, they cost more than traditional speed bumps.
