When I test drove a Tesla for a weekend my opinion of the Autopilot was the same as the car's owner: "It drives like a learner driver". Just like the nervous parent teaching their teenager to drive, this is not a relaxing experience.

However, the speed-adaptive cruise control is the best I've ever experienced. It maintains the set speed exactly, slows down for corners automatically, and follows the car in front as if there was a steel rod connecting the two vehicles.

Using the cruise control in the Tesla was some of the most relaxing long-distance driving I've ever done in my life...
