Yes it would. Those track targets at a few feet, meaning all that shaking it's doing when it's "Pointing" would just wave the laser around in the general direction of the car that is much further away. from 4-5 feet away, a person with 2 foot width ~= .5 radians or 28 degrees of pointing accuracy needed, and no tracking accuracy needed since it doesn't seem to follow targets well. (that second link the target is all of 2 feet away and 1 foot width). 100m away, an aproaching car has 2m width ~= 1/50 radians, or ~1 degree of pointing accuracy. More to keep on center of mass. And a car at that range would be about 20 pixels wide. That doesn't inspire feelings of robust visual tracking the way "Big blue blob of paper that fills 20% of the view" would.
