Partially why it is expensive. The fact that it is easily damaged makes
maintennance that much more expensive. Not to mention constant replacing of
paper track would eat up valuable event time.

Pick a color and publish the mix codes for that particular color, brand, and
sheen on the web so that others may go to a hardware store and request that
particular mix. Can't do that with inkjet or laser printers.

Limit the number of racers to something reasonable... 2 or 3 bots.

All race cars for a given class of racing are pretty much identical. With
all things "chassis" being pretty equal, that means the competition is based
more on coding and steering than overall bot structure. In real racing, you
can have the top-notch car, but if the driver doesn't perform well or is
involved in a crash that totals the car, they may not win. Guess it all
depends on what the overall learning experience is supposed to be.
