Cars with those stupid HID bulbs so bright white light its like daylight.
The other night I was traveling in my car down a country lane I did not know with lots of humps and hollows and bends- I get this git in a merc behind me right up my arse with lights so bight they were casting a black shadow of my car in front of me and everything else each side of this shadow was bright white it was like driving into a hole, I had to slow right down to 20 mph which made him get even closer which made it get even worse which ment I had to go even slower, there wasnt even a good spot for me to let him pass.
