Well for what’s it worth my VW Tiguan does that as it has the “Traffic Plus” option in it that adds the line assist, adaptive cruse and stop/start together along with steering around the bends however I don’t think you can call any of these systems “Self Drive”.
If I take my hand off the wheel I get nudged to take over the driving and as we now have third world roads it hard for the car to see the white lines on the road anyway though Motorways are generally OK. I have to admit its a very nice option to have and has made driving for myself, one handed, very easy regardless of journey length but no, there not self driving, just assisting.
What I would call self drive is when I can program the satnav to take me a hundred miles then wake me up when I get there but that’s IMO is still a couple of decades away.
