That’s interesting - we have them in place at several occasions here in Germany (as the article mentioned Europe). They work the other way round here, though: They are green, and will turn red if you speed. And yes, most of the time, people will match the speed so that it will stay green. However, depending on the implementation, sometimes you can get away with speeding, and the cars after you will be stopped.
