A system, method, and computer program product which normalizes GPS data obtained from multiple vehicles. At a server, GPS information is received from first and second vehicles in first and second formats. The GPS data is normalized for synchronized display of positions of the first and second vehicles, and transmitted to a computer in order to display simultaneously the synchronized positions of the first and second vehicles. An end user of the system may search for GPS logs of other people and simultaneously display the information resulting from the search with his or her own GPS information. The system may also provide for an automatic upload from a mobile device of the GPS data captured on a circuit or other location.
