It's only a matter of time until other manufacturers come up with an "auto pilot" so I'm not completely surprised to hear that Mercedes has developed a better system. Not sure it can do over the air updates like the Tesla. Being a Tesla owner now for 7 months, the autopilot is easily my favorite feature i use it all the time. 2nd favourite feature is over the air updates. Interested to see how autopilot has changed since i've purchased the car back in October. The AP that is currently in the car is definitely improved over the version when i purchased it. Its cool to know that it will only likely get better and I don't have to pay a cent for it. If the mercedes can't do this (and I suspect it can't), it is a bummer for a developing technology.
