To this point, if you note the small print in the ad, it states that a
safety line was used to PREVENT the car from sliding down.

Well Christ, it's a fraud!!
"The Audi A6 4.2 quattro with 6-speed tiptronic that drove up the ski
jump was otherwise a perfectly normal production version. Two minor
exceptions: the automatic transmission was kept in first gear - the
slight power loss that occurs when changing gear would have made it
impossible to climb such a steep gradient - and the tyres'
six-millimetre spikes. Tyres of this kind are also used in rallying."
"Minor Exceptions"?? 6mm spikes??? My Vette could make it up that
hill with freakin' spikes!

My experience with a hill nearby, (about 25 to 30 degrees) grassland.
Easy to climb with 4wd engaged, no spinning wheels. In 2wd mode the car
won't move an inch, the rear wheels were spinning though (LSD).
Kind regards,
