I've been thinking about starting a similar thread for a while.
one of the things that annoy me is people who exit the motorway without indicating, or indicate with about 50 yards to go.
At the Adanac roundabout, people who biťch and moan when I use the right hand lane to go over the roundabout towards Lordshill. That's what the lane is for, dickhèad.
There are many others, but that'll do for now
