I don't have a self driving car, but my 2017 Honda CRV EXL does have some elements of that.
Shortly after getting it I demonstrated the car to my nephew, I turned on to a curvy road near my home going south from Cannonsburg MI.
I said to him, "Watch This!" and set the Cruise for 55 Mph and set my feet flat on the floor and took my hands off the wheel.
I did keep my hands close to the wheel, we proceeded down the road at 55 Mph with the car steering around the corners.
About 3 miles down the road a car pulled out of a side road in front of us, the Honda put on the breaks and slowed down then accelerated to keep pace with the car.
It followed the car ahead matching it's speed for another 4 miles or so, until the car ahead reached the stop sign at a T at the end of the road.
The Honda slowed and came to a stop behind the car. During this period I had not touched any of the controls.
When the car ahead pulled away the Honda started up too, and I had to quickly take control and turn around the right angle corner or zoom across the road and into the ditch.
But it gave me a real feel for what a self driving car would be like, I don't do this normally on secondary roads, as it is really harder to sit there ready to grab the wheel then it is to drive.
Now I use the lane control and auto braking as a reminder on secondary roads but often let it steer and control the speed on expressways though I have to say I always stay alert because I still don't trust it enough to relax.
But self driving cars are coming.
There was a fatal accident involving a Tesla where the driver was watching a video on his tablet while letting the Tesla drive.
A truck with the rear so high off the road that the Tesla didn't detect it stopped in front of him and he ran into the back of it.
They have updated their system as a result, but I think it will be a long time before I feel comfortable enough to not pay attention when I'm in the driver's seat.
My wife on the other hand doesn't trust it at all and won't use the auto cruise or lane detection at all.
