Because the more information you have to make a split-second choice, the better- i.e. choosing to hit some debris that rolls out in front of you instead veering into the path of a car; or choosing to T-bone a car that pulls out of a driveway, rather than veering into the path of a truck going 60MPH. Having to turn one's head and look/glance in the mirror, may not be an option in a split-second decision- but being fully aware of your surroundings at all times can help one make the right/better choice.
