OTHER USEFUL MYBLOCKS
"DisplayPosition" and "DisplayVelocity" are two handy myblocks which you can insert into the "MoveCar" myblock during the main loop in order to have a position vs time and velocity vs time respectively show up on the display of the NXT as the car moves. These have not been tinkered with in a while and I may have broken them by updating other things but try them out! I'd be happy to fix them if I knew there was interest.
