Answer 1

this is one thing

The Beginning...
As times change so doth the partying at the Speedway. During the
race in August 1909, the cops were out in force and anyone caught
drunk was escorted off the property. Politeness was enforced.

Through the years, the infield of the Indianapolis Motor Speedway
has served as a giant parking lot, a Golf course, museum
headquarters, and garage area. It has always been a popular place to
watch the race as well.

When America drove Model T's, people could park along most of the
inside edge of the track and watch the race. Of course only the
first row or so could see.
