In my experience the 20mph speed limits that Leeds City Council have implemented have actually made the speeding problem worse, it seems most think that that the signs actually mean 40 mph, there’s one area with a left hand bend, with a primary school and crossing just after the bend, I’ve been overtaken on that bend whilst doing the allowed 20mph, the vehicles that obey the limit can be counted on one hand, it‘s no good instigating a lower limit, unless the police are involved initially to, shall we say, promote the initiative on motorists who won’t comply.
