Tesla Motors isn't usually a company that advertises itself. It doesn't have to. Tesla owners do most of their advertising for them, from word of mouth, to shooting fan made commercials, to giving people rides in their Ludicrous equipped P90D Model S. 

There are times however that a company needs to show the best of what they offer, and autopilot is a feature that pushes the boundaries of what a production car on the road can do. Having used it myself in a test drive of a P85D, I have to agree that it will make driving more relaxed, and I cannot wait to use it on a daily basis.
