In Albuquerque NM a few yrs back , gang initiation was for the " wannabe " to go out driving at night , with their lights " OFF " ( this is important ) . When you met an on coming car and they flashed their lights , to remind you that your lights were off . The " wannabe " was to make a u-turn , chase the other car down and shot at it , trying to kill everyone in the victims car . The reason I know this is because I lived/ worked in NM for 10yrs . It was local news at the time .
So if you see someone driving at night with their lights off , is it just someone who innocently forgot to turn on their lights , or a drunk or " gang initiation " ?
As far as road rage . I just let it pass , won't honk my horn back and I try to remove myself from the situation as quickly as I can .
