I keep it at 70 on the highway. There are times I have to slow down to get behind slower traffic so the autobahn drivers can fly past me.

As for Tesla. Today for lunch I walked to the Stanford Shopping Center (and, by the way, had a pretty excellent grilled salmon chowder), but I digress. As I walked past the Tesla "store" the sales guy looked VERY bored...but the Apple store was hopping.
