Lane markings, either arrows or road numbers seem to be beyond the grasp of most drivers around town. Again today I've been in the left lane on Eastgate street turning into North Walls (clearly marked A518) & 2 vehicles in the right lane (clearly marked A449/ A34 south) just nonchalantly pulled across the front of me into the centre lane on North Walls (clearly marked A518).If that is the case then an awareness of those also on the road with you is a helpful driving skill when unfamiliar with local lane discipline!
Don't even mention the lanes at the Asda roundabout, the signs & road markings obviously aren't big enough for the wankers that either sit in the middle lane of Lamascote rd to go up Queensway or the wankers that sit in the left lane & then cut across the clearly marked lane to go up the Wolverhampton road.
