Proxy racing typically involves building a car and then mailing it to another location where it will be matched against similar cars in a race.
Cars are usually built to a specific set of rules, then mailed to a central location for tech inspection. The cars are run in a series of races by guest drivers, with points allocated according to finishing position. All points gathered go toward a grand total for the race series.
Slot car proxy races are often accompanied by a Concours d'Elegance, a contest where entrants compete for the best looking car.
Slot car proxy racing enables car builders from different parts of the country, or even the world, to compete on an even basis, without the expense of actually being there.
