if you flash your high beams at me your gonna get blinded and run off tha road...sorry but its them nokya bulbs its not my fault
Interesting - over here in the UK, flashing your high beams at someone means "OK, you can have right of way" eg if someone is waiting to pull out from a side street and you are driving towards them, a quick flash on the high beams means you're willing to let them pull out in front of you. UK Toyotas even used to have the high beam "trigger" labelled "PASS"
*Edit and I just realised I kind of missed the point of WHY they were flashing at you... doh!*
