Since the "take extra time to look out for bikes" adverts has been running, I've noticed a sharp increase in the number of cars pulling out in front of me - many of them not taking ANY time to look out for anything. The only time I noticed a reduction in cars pulling out was when they run the seatbelt ads showing a truck pulling out in front of a car, that ad did more to prevent motorcycle accidents than it ever did to get car drivers into seat belts.
