As Bikebiz said you need vision to the lanes on your left and right, a head check and moving your elbows will often give you more than enough vision behind you when necessary, but its important to be able to scan without actually moving to see whats around you, rather than directly behind you.
For the same reason its important to be aware so you know when cars move into and out of your blind spots, coupled with checking blind spots just to be sure
