The curiosity of Auriol (Lauriole)

This is a fantastically wierd 'anomoly' to visit. 15 minutes away La Curiosite de L'Auriol is a stretch of road that is one of a few in the world. While your sat in your car if put it in neutral the road looks like it goes down (forward) however you will roll backwards, this is caused by the scenery. If you google the french name you can see people on youtube trying to figure it out.
