Imagine a world ruled by blue people, who control all the roads. Every time a green person tries to drive a blue person will throw rocks at their car, pour oil in front of the wheels, etc. Also for historical reasons all the green people live in certain neighborhoods. Now imagine creating bureau that would review driving and accident data and attempt to answer the question "How good at driving is this person?" The idea being that we are going to try to keep the worst drivers off the road. People scream hey wait a second that's not fair at all. So you take steps to address this whole system instead and solve the real problem. You try to crack down on all the rock throwing, and not prejudge someone without knowing the circumstances. Until one day an algorithm comes along to answer the question. But wait, we thought of that, we make it so the algorithm can't take into account what color the driver is. It can only rely on other things. See the problem yet?
