Everyone must have seen the roof top test/track on the Fiat factory, used in The Italian Job. There is/was another one, that I have never heard of before!
A Belgian car factory, that originally made an extinct marque, Imperia, was later taken over by Standard to make Tens in Europe. Although Standard never used it, Imperias were tested on this dangerous looking track with extremely narrow steep corners.
You can see it on a Club Triumph thread at:
http://club.triumph....896/s-15/#num18 The latest contribution shows that today, only two corners remain, and a large hole on the on-ramp, so there is no hope of getting a car on it now, let alone driving it.
BUT! I know that people into Virtual Racing can design their own tracks and drive them. Is it possible to recontruct a virtual Nessonvaux roof track, and put a cars on it? Anyone like to try?
