The Chalmers-Detroit racecar is NOT at any Detroit race track. The Chalmers car company began in 1908, 7 years after the Ford-Winton race. Chalmers cars were tested at the Detroit Driving Club, however, but not raced.

As far as kerchen goes, the 999 wasn't even built until a year after the Ford-Winton race, and was 1st driven by Barney Oldfield.

Regarding historical accuracy, auto racing was over by 1905, at the Grosse Pointe track. This track looks more like a track in Indiana... hmmm.
