The rare occasion when one pulls up to an intersection. The cars,in front of you, that want to turn and have their blinkers on, the blinkers, which are an amber color, start blinking in unison. All going on and off at the same time, in a perfect accord. The effect only lasts at a maximun of 3 seconds.
Yesterday at around 5:30, when i was at a red light, i saw The amber effect happen right in front of me when 5 cars were wanting to turn left! Shit was so cash
