One road that annoys me is the A4119 through Groes Faen. Camera's at either end of the village with a 20mph speed limit. Always a ballsache to drive through.
In fact the rest of the A4119 towards Cardiff is a mess. Variable speed limits (I've mentioned this before) ranging from 20 through Groes Faen to 30, 40 and 60 in different places but so many cars drive at 20 - 30 all the way along. So frustrating.
