Looks like those pics were taken near the Gross Glockner(G.G.)... probably testing the brakes for fade and for noise levels (hence the microphones on each fender!). When I drove the G.G. last year I saw quite a few testwagen cars testing thier brakes on the decent.

That is a nice little bier garten with some 200 annimals near the North enterance to the G.G. Here is some more info IF anyone wants to go for a visit.
