Whilst staying with Varche we decided to take a trip up Top Gear's "road to nowhere" near Granada in Spain. It turned out to be quite interesting. Firstly, it doesn't actually go nowhere. There's a ski resort there:
The view's quite nice:
There is also a coffee shop at the top, a couple of observatories, one old and ruined, one modern, with what looks like a radio telescope. Height at the top of the road is about 9000 feet above sea level. Anyway, the more interesting thing is that there was clearly a lot of car testing going on.
I spotted a couple of "mystery cars" with bodywork obscured by stick-on panels and defensive paint patterns. Some ordinary cars had "lumps and bumps" on the bonnet, suggesting something unconventional was being tested underneath. One car I saw had some unconventional looking connections by the fuel filler. Picture quality isn't great as I was watching from a distance without a long lens:
These cars were being driven up and down the hill constantly by a team of drivers, all with laptops plugged in. Periodically, there'd be a driver change, and the exiting driver would sit down with a coffee and have a good rummage on his laptop. Lots of apparently standard VW/Audi cars were doing this in addition to the disguised ones. The top two cars above I caught sight of doing a standing start up a section of mountain road when they thought nobody was around and 'kinnel did they take off!
I also spotted a couple of cars towing these, or variations of them:
A smallish trailer, but look at the size of the wheels, and the cooling ducts! This thing was putting out quite a heat haze when it pulled up! "Towing dynamometer", apparently. I guess it's used to retard the car and simulate towing without the embarrassment of having to take a caravan with you.
