Well, you'll see that his location is San Francisco, in the middle of a major drought. A lightly oiled roadway with a light rain is damn slippery, but a good learning experience in handling his vehicle in less than optimal conditions.

He didn't say where in the City he was or what highway he was entering, but recently built on-ramps are long and straight to allow synchronizing with the 85 mph traffic.

I always used and use an empty parking lot to find the limits of adhesion. As soon as we get a light snow this year then I'll be out learning xDrive and a vehicle half again as heavy as my VW.
