They are talking about making speed limiters based on this technology mandatory in the next few years and I am dreading the day I tootle down the bypass at a perfectly legal 40mph only to have the limiter kick in at 20mph because it's picked up a roadsign on an adjacent road. This kind of mis-recognition happens all the time, but in the current car it is not connected directly to the limiter and merely flashes up an annoying warning.
My new 70 m.p.h road sign stick on camera stickers buisness will be up and running by then
