What color be dat light? Who give a f---!

Colour-blind man's 'dream' comes true as he gets green light to drive Tube trains

A tube driver who suffers from a form of colour blindness is believed to be the first in the world with the condition to be allowed to drive a subway train.

Alex Bulley, 26, has been permitted to work on the Jubilee line because it no longer has red and green signals and uses automatic trains that “drive themselves”.
It drives itself. OK. Then why not just let a hamster drive it then?
