Agreed. Most people (eg. families) in Germany drive about 70 mph in the right 2 lanes. It's just the odd-ball $100k+ M-B S class or odd-ball Porsche that rips by at 100+ mph. Odd-ball meaning...in a blue moon...especially in the case of the Porsche. There are more of these found on the streets of So.Cal. than seen in one day of driving/sightseeing in Germany.
That said, a lot of higher end German cars (eg. my BMW) have oil, tranny and rear diff. coolers that are omitted in the U.S. market. Also due to high speed driving...and still use the viscosities recommended above. Imagine using a 5-20 w/o the cooler and driving in AZ's 100+ F at 100mph?
