I don't think you're being very accurate there. There are lots of videos of people commuting 50+ miles to and from work every day without touching anything while on the interstates, including interchanges. It's doing a lot more than just lane keeping.
Perhaps you should check more frequently? Here is a video of a Tesla on Autopilot stopping for a stop sign:

> “The car always stops at the end of a highway exit since Navigate on Autopilot. At the stop, you just need to touch the accelerator to start Autopilot again without Navigate on Autopilot. I didn’t accelerate, you just need to touch the accelerator for less than a second and the car will do the rest at the intersection.”

Which cars have you drive with a superior cruise control implementation?
I feel like people forget human drivers hit those same barriers with alarming frequency.
That being said, Tesla's cruise control capabilities are best in class, but it's misleading marketing-speak to call it true self-driving.
What I mean is, you are not providing input to the wheel, or pedals, or turn signal or driving the car in any way. You're just letting it know you have not fallen asleep.
And, yes, thanks for asking, I have used it.
