Don't know what my clan will have to do, the nearest motorway is 120 miles away.
Oddly enough, whenever I have the misfortune of having to use a motorway, I'm not the one wavering around in my lane, hogging an overtaking lane, blocking a car on my left from pulling out to overtake, etc. etc.
All those morons I can compensate for, but the most annoying of all is almost the opposite of a lane hogger, it's the guy who pulls back in too soon when overtaking when there's no need, covering me with whatever grit and rubbish his tyres can ping up.
Rant over.
