Numberplates for bikes?
re: the numberplates for bikes argument. How about we do a swap? Lots of cyclists get hit by drivers who fail to stop. We could locate them with a tracking device in their car. Similarly, this could also be used to stop drivers speeding and jumping red lights - I tend to view two tonnes of Mercedes Git Panzer going through a red light as rather more dangerous than 100kg of cyclist + plus.
So a fair swap - we get numberplates and you have a GPS activated tracking device and speed limit monitor?
