Wild guess but the Vanderbilt Cup races held from 1908 to 1911 ran on a course in Savannah, Georgia. USA.
It had long straights up to 5 miles long and ran past trees "bearded with Spanish Moss. "
So it can be seen that this has not been a race track for a long time and the cars drive on the right side etc..

(Am I getting close Ray ?)
p.s. It was the Grant Ellwood tip that helped me, thanks.
