The thing is, Googles self-driving cars won't get to you overnight. We may already have the technology, but it's too complex/costly for a normal car yet. (70k$ radar, a rack of servers)
But what you will get is more and more autonomous features until there is the first fully autonomous production vehicle. And this Mercedes is one of the first bigger steps in this direction.
Well, as many mentioned, 70k might not be so much for trucks... autonomous delivery of goods and services probably will save A LOT of money (and the driver doesn't need to sleep :) )
