Makes me wonder how much of the logic was in the cars themselves. I'm guessing not much. Might be a fun weekend project to try to hack though

The car's on-board processor has enough logic to follow the track lines hidden under the track surface. The BTLE connection to the car is used to control speed, change lanes, and trigger lights. It also is used to 'drive' the car in some cases if needed.
