This is the first-of-its-kind remote controlled racing set that uses an artificially intelligent track to assist steering through turns at 180 mph scale speeds. Only available from Hammacher Schlemmer, the durable vinyl racetrack assembles from 20 pieces in minutes, enabling drivers to configure over 40 different track layouts, including some that use a flyover bridge to create crossover circuits. The slots of conventional tracks are replaced by sophisticated artificial intelligence that determines a car’s orientation on the track, automatically compensates for angle and drift, and helps drivers cleave to the track even as they attempt tight turns and daring passes. Competition modes allow for races between 10 and 999 laps—solo mode allows a driver to compete against an AI-controlled “pace ”car”. The 2.4 GHz wireless pistol grip controllers provide in-race announcements of lap times, race position, required pit lane visits, and even random hazards to which drivers must react. Two cars run for four hours on three AAA batteries each; each handset requires three AA batteries. Ages 8 and up. 21 1/2" L x 20 1/4" W x 4 3/4" D. (4 1/2 lbs.)
