The term "races one motor" can be interpreted in a few different ways, but assuming it means to drive a car or motorcycle at high speeds for competition, some antonyms might include "drives cautiously," "travels at a leisurely pace," "cruises calmly," or "flows steadily." These words suggest the opposite of racing, indicating a slower, more laid-back approach to driving. Other potential antonyms could be "follows the speed limit," "obeys traffic laws," or "drives defensively," all emphasizing safety and adherence to rules rather than competing against other drivers.
