What you seem to be describing are driving assistance systems to aid with safety – they are nowhere near ‘self driving’.
Some people love them (me) others hate them (my wife).
My Toyota CHR (not electric- so outside your list) has what I consider to be excellent Adaptive Cruise Control & Lane Guidance / Lane Keep Assist. It will get very cross if you take both hands off the wheel (and there’s a heated steering wheel to encourage you to keep them there too!). I’m not aware of navigation systems that slow the vehicle for bends – which sounds like a step too far for me!
