""Ken--I grew up on the GM Milford and DPG proving grounds, but I'm shocked at that bank angle!! I know ours were designed for a neutral angle at about 150 in the high speed lane but they sure didn't look like that! Regardless, I've never had a GMC on those tracks but it sure can be unnerving even in a Vette or Camaro.

I guess I'm not impressed.
Several times in my career I either worked at or was assigned to the Chrysler Proving grounds.
Go to Google Earth and find N42 16 W084 03 to have a better look.
Or read:

The bank angles aren't that high, but they don't have to be because it is on more than twice land area the of the Unterturkheim track. When Germans moved in, they could not believe the magnitude of the facility or the capabilities we had that they had been able to developed. (They had a lot of very candid conversations when they didn't think they were being understood by Chrysler people - My mother was born in Frankfort on Mein.)
When I worked as a part of the facilities department in the early 70's, I had to supervise work on the high bank. To map the pavement flaws, I had drew a something with a big block and crash helmets and had a driver take me around about a dozen laps at varying speeds up to and over 100. I had planed to make notes, but all I could manage was x's in the track diagram. I do not remember the actual bank angle, but it is real hard to stand on. One concrete mason looked at me and jokingly asked if he was working on a road or a wall.
No, they never had a Travco/Dodge on the high bank. We did have a good number of them as instrument vans.

OK, not a test track or a GMC (but I do tow my jeep there WITH the GMC) but here is another type of high bank turn:

This was taken at the Imperial Sand Dunes in California. The 'bowl' is as steep as you can pile sand and the top speed is only about 30 mph. The first video is of me and the second is of my nephew. It takes some centrifugal force to keep you on the face of the dune, but if you get in trouble,you just have to head toward the bottom.
