Worth remembering before you overtake, let's say, a car signalling left. The driver may THINK he is signalling right!!!!
I've had people turning right from the left lane of a roundabout.
Twice this week, on the same road I've had a car start to undertake me on a single lane road. I wasn't even out wide looking to filter. I could understand maybe if I was in London, but this is a small town.The only way I can think of stopping this is moving further inboard on the road, but that compromises my view of the road ahead.
