hi matt
its not so much the head lights but the gangs of guys walking up to the car before its even stopped and then wait by the side of the car like its there god give right to watch or laughing and joking next to the car some couples think there being laughed at
if you are clean on your own and discreatly wait and move away when a car comes in it will happen
how do I know simple its the way we pick the odd guy
best of luck mate!!
