The first purpose-built for car racing circuits. Milwaukee?

I ran across this information as I was putting together more research on motorsports. I was so disappointed with the Indy Car race this year when the fans in the Milwaukee area just did not show up for a great race. I know for a fact that the actual promotions for the race did not happen until two month before the race. Their was no interaction with local businesses at all. No grocery stores were involved, and no gas stations promoted this race at any level. No product branding and contest for free tickets, or heck not a thing but some radio and TV advertising a month or two before the race? I did grow up in Indiana with such an major thrill of the Indianapolis Motor Speedway so close to me. I have been in such a major excitement of information over Indy. So much news has been in play about the Indy 500 and the history. Well the Lord brought me to Milwaukee area for the reason of letting me know even a major fact in my motorsport quest. The Milwaukee Mile!
The Milwaukee Mile is the oldest motor racing track in the world, with racing being held there since 1903. It was not purposely built for motor racing, it started as a one-mile (1.6 km) horse racing track in the 19th Century.
From 1903 to 1914, a one-mile dirt oval track was run on Brunots Island, just south of Pittsburgh on the Ohio River. Louis Chevrolet won the AAA Champion car in 1905. On September 10, 1907, Rex Reinersten was fatally injured in a crash here. In 1916, Chevrolet won the first Universal Films Trophy at the mile and an eighth Uniontown Speedway board track,. south of Pittsburgh in Hopwood, PA.
A remaining section of the Brooklands track today.
Brooklands in Surrey, England, was the first purpose built motor racing venue, opening in June, 1907.[7] It featured a 4.43 km (2.75 mi) concrete track with high-speed banked corners. Brooklands was also a centre of the aviation industry, with Vickers setting up a factory and aerodrome there during World War I. The racing circuit was closed in 1939 as war-time aircraft production took over. Damage done to the track during World War II meant the track never reopened for racing.
Competition gradually spread to other parts of the British Empire. The first competition in India was held in 1905 by the Motor Union of Western India. It ran from Delhi to Mumbai, (Delhi-Bombay trials 1905) a distance of 810 miles (1,300 km) in an attempt to expose India to the automobile and test its suitability for Indian conditions. Lord Curzon, the Viceroy, gave his consent to the event.
