How accurate can a line following robot be? (Laser cutter idea inside)

I have no idea how accurate line following robots can be (and this is what I'd some clarification for), but could a cutting laser be mounted to one? The robot would just follow a black line that you've printed out, and in the process would have also cut out the pattern. If that would work, this would allow you to cut out shapes from a huge canvas size, as well as making quick stencils with a fine line Sharpie.

A line following robot can be accurate, just depends on how well you have programmed your microcontroller, and how many IR - sender - reciever pairs you have (of course, the more you have the better, but some microcontrollers can only have about 6 - 8 pairs connected).
. Yep. You can get as accurate as your budget will allow.

I built one from lego, once, and the biggest con would be the hysteresis. Most line followers, since they can only see 1 or 2 points, have to correct themselves while already off-course. The result is a wavy line. A LOGO Turgle might work better ;-)

While the idea is good, there is one problem. Most, if not all line following robots are unable to follow angles of less than 45 degrees. So, yes and no.
