Are you serious? When you're driving, and want to switch lanes, what do you do? I personally check my rear view for a split second, then my side mirror then a quick head check for blind spot.

EVERYONE who drives should do this. I see morons on the road who just check their side mirrors and cut over, not realizing that there's another car right next to them, in their blind spots. That's how accidents happen.

I'm just curious, other drivers out there, do you check your blind spots?
