Had a good one today, although not a lane hogging thing.
Coming off a roundabout woman pulls out of side road a bit late, so I have to start slowing down, all of a sudden she comes to a skidding halt, nothing in front of her; pouring down with rain.... sooo close, slammed on and (luckily) went into the dropped kerb of sometimes drive, otherwise it would have been a damaged wheel for sure.
Then she tried to get moving, but the car was hanging... it looked like the handbrake had come on (electronic perhaps), but she was there for a good 20 seconds, with it pulling aginast the brake.... glad I had some decent rubber on there (AS2's) or I wouldn't have stopped... mind you without the evasive action I would have.
