Been passing this guy morning and evening for a few years on the M4 between Bridgend and Newport travelling at seriously inappropriate slows speeds perhaps 40 mph. Agreed with other posters, this moron cause chaos around him. Going back a couple of years ago, he used to do this in the middle lane, small mercies - at least he uses lane 1 now. If for some reason he needs to drive this slowly, either he and/or his car shouldn't be on a motorway.
Yes it's wrong, but I'd also like to point out that foot-way is very wide. Let it go?
