In London we are getting more and more 20mph roads. My son has just been done for doing 24mph and a mate just been to a speed awareness course for doing the same. He told me there were drivers on the course being done for 22 mph!!! Biggest problem is trying to stick to this limit without some twat of a driver behind tailgating you driving about a inch from the rear of your car often flashing there lights and occasionally passing while waving a fist at you. Seems to me it is causing just more road rage rather than saving lives. I just think it's another money making tax.
