I can't work out if these are worse than inattentive driving or not. I mean, it's deliberately aggressive, but (you hope) they aren't actually trying to hit you, just give you a scare. I think an inattentive driver is probably more likely to hit you.
Doesn't happen often, but had a couple recently, one just now coming back from the protest. Riding up the Bridges in the bus lane, I was going to turn right up the Royal Mile, so keeping an eye on the traffic. Big gap coming up, so around 30-40 yards from the crossroads I move into the right lane just as the gap appears. That lane at the crossroads is right turn only. Peugeot Coupe is going straight on, but has clearly just swerved out from behind me into the left lane and then moves back into the right (turn only) lane to go straight on. Quite clearly making a point. This all within 5-10 yards of the crossroads, by which point the lanes are very clearly defined as straight on and right turn.
