I don’t 100% believe this, but it tickles me anyway.
Supposedly, car-based flirting in Iran avoids the (potentially illegal) need to be alone with a member of the opposite sex:
Rules of the game? Pile in a car and head with your same sex possie to one of the city’s flirt strips, cruise up and down until you spot a likely target, being careful to pick a car that’s broadly your car’s equal and then aggressively use tail lights, fog lights and rear windscreen wipers to initiate the courting ritual. A response is equivilent to a pick-up and the cars cruise side by side to arrange later rendezvous through open windows and over the sound of preferred music tastes.
The advanced version involves engineering an accident as an excuse to get contact details.
Downside: it’s only a matter of time until the Pick-Up Artists get hold of this and start systematically rear-ending girls’ cars.
