Not that simple...
I was once stopped at a red light when a fire truck approached me head on. If he wanted to go a certain direction, then I'd better move to the right. But if he wanted to go another direction, then I'd better move to the left.
Which direction was he going? The front of the fire truck was covered in about 17 flashing lights. There was even a blinking and spinning arrow.
It took me several seconds to find his blinker among the visual clutter.
Good luck Google.
