Might be true, might not be. Allegedly originated from an internal memo from the Metropolitan Police. There's a new initiation process for idiots wanting to join street gangs. What they have to do is nick a car and then drive it round the streets at night with no lights on. The first car to flash their lights at them, point, sound their horn or otherwise attempt to attract their attention (to the fact they haven't got their light on) they then have to follow it and put at least one round into the car. No matter what they car is or who's in it. Therefore you are advised to ignore any car travelling at night without lights on. True or false?
