Not quite the same, but I was driving to work today, and on the way there it's mostly single lane except for at traffic lights where it splits into two lanes for a little bit before and after the lights (so people can turn etc). Anyway I'm waiting behind a car turning right, and there are a few cars in the left hand lane going ahead, lights go green etc car infront turns left, I take off (accelerated kinda quick, but nothing stupid) and some dope infront decides to suddenly veer into my lane, then proceeds to drive with his wheels either side of the white lines.
I wasn't any where near hitting him, but fuck :\ no indication or anything.
