Roundabout discipline is something that really winds me up.
I think basically people forget the basic rules of roundabouts as written in the Highway Code.
Well done Lum for your fast reactions, and possibly a shoulder check would have sighted the kamikaze shopping trolley earlier.
I really don't know what's so difficult to understand about roundabouts.
I think that the more the authorities try to stop bad lane discipline on certain roundabouts, such as kerbing in the left-only lane Lum described, or painting huge arrows all over the lanes, the more the offending drivers forget about the standing rules for all roundabouts.
It's getting to the stage where almost anything goes and it's starting to get both dangerous and very annoying (provoking more road rage incidents).
I wonder what would happen at these bad roundabouts in heavyish traffic (where the tricks seem at their height - round here anyway) if a couple of BiBs stood on them watching all the traffic.
Would people miraculously sort their acts out or would they carry on as normal, turning in wrong lanes, 270deg queue jumps and all?
