Speed bump

The German city of Hanau in Hesse plans to adopt a Swedish approach to speed bumps. Although they are often a good way to reduce the speed they are also a pain for people who obey the speed limit. In this approach a metal plate in the street will get a radar measurement and allow cars which are within the speed limit to comfortably pass, but it will lower itself and present a hurdle for cars that exceed the speed limit.
