I was wondering if anyone would like this idea, GPS file (.gpx) upload to create a new track.
So you could bring your phone with a GPS app to a track and record your laps to a GPS file, then upload it to GT when you get home, GT will then it build your track based on the file you uploaded.
You can also drive your favorite mountain road and do the same thing. This way we won't get stuck with the random track build and hope for the best.
You can still choose your environment, forest, desert etc.
What do you guys think, or maybe somebody posted this idea already.
