Don't you hate drivers that indicate after they've started to turn?
I was at the round about and a guy opposite me started to go straight and then half way through he started to turn and indicate to his right and then 3/4 of the way through he decided to go full circle. Like Newsflash! Even i dont drive that bad.
And no i dont care if there are no other cars on the road...indicate anyway.

this story is for those who are going for their licences (donna i know its you) and those who think that they are too good to indicate.
