I wonder why some people change personalities when they get behind the wheel of a car.
9 times out of 10, when I'm backing up and someone drives up, they swerve around me instead of waiting for me to finish backing up. Same applies to people on foot, they can see me better than I can see them, but they will continue on.
Or you're driving the speed limit and they just have to pass you, get in front of you, then make a right turn. What's with that?
