The vehicle is not capable of more than 60 km/h when used in self driving mode, so the reasoning seems quite logical. I wouldn't want to use this on the Autobahn though; everyone would be overtaking constantly which introduces additional risk, and the speed is so low that journey time would be considerably inflated.
