I found a HUGE glitch in Porche Unleashed!!!!
 

In the track "Shwartzwald" (or however you spell it), in the small town, on the left there are small spaces between the houses. If you drive into one of these spaces, you can turn into the walls and drive into nothingness. It's really cool. If you put View distance on full, you should be able to drive around the track on the "outside", or use the map to guide you.

Whats cool with that. I tried it and thik it sucks. Whats the poit?

I found something similar on Zone Industriale, it was so wierd when it happened that I kept the reply, just to see how I did it. Well at least it passes the time.
