I don't understand the basic premise of why you'd even make this app.

Why would someone use an app to research tracks?
Wouldn't people prefer to use Google and a full size PC or laptop?
Do people research racetracks while "on the go"?

Also, most people are within living distance of 1 or 2 tracks.
They probably already know about them

I don't get the GPS aspect either.
Do you think people will randomly go to a track b/c they were not aware they were driving past one?

I don't see much of a market for this app, but it sounds like a nice hobby project.
