A college student who was late for his physics class drove through a red traffic light and was stopped by a patrolling policeman. He is trying to explain the policeman that the red light appeared green to him due to the Doppler effect.

How fast did he need to drive for a Doppler shift this large? (For red light use 677 nm, for green 540 nm as wavelength.)
