Done a lot of motorway and dual carridgway miles this week ( M1, M25, M4 and A45 ).
SWMBO says I'm starting to suffer from GOMS (grumpy old man syndrome) as I expressed my irritation (frequently according to her) of drivers at junctions, who just before the exit slip road who are in the outside lanes, intead of dropping in behind you and exiting, decide to put their foot down, overtake you and then "swoop" across your lane, frequently cutting you up, and exiting at the last second before they miss the junction.
Also in heavy traffic and roadworks those who weave between lanes over and undertaking.
Also frequently seem to be executive type cars with a 3 or 4 letter brand name.
