Car racing system

A car racing system, comprising:

• a lane (100) configured for car racing;
• a first car and a second car identical in structure, each car including:
• a car body having a first part (210) at a front end of the car body, a second part (220) at a middle portion of the car body, and a third part (230) at a rear end of the car body;
• a first magnet (211) disposed at the first part of the car body;
• a first locking device (225) coupled to a bottom surface of the car body, the first locking device including a first locking portion (226);
• and
• a second locking device (235) movably mounted in the car body, the second locking device including at one end a second magnet (239) and at an opposite end a second locking portion (238) that engages the first locking portion (226) of the first locking device to lock the first locking device;
• and
• a remote controller (300) for controlling at least one of the first car and the second car,
• wherein as the first car approaches the second car from behind such that the first magnet (211) of the first car is brought into proximity with the second magnet (239) of the second car, the second magnet (239) of the second car is magnetically attracted to the first magnet (211) of the first car, causing the second locking device (235) of the second car to disengage the second locking portion (238) from the first locking portion (226) of the second car's first locking device (225), thereby releasing the first locking device of the second car and lifting the second car upward off the lane.
