Adaptive cruise control, tech we've had for what, 20+ years? is more than enough for most highways, it takes out ~80% of the stress/boredom of driving, especially since lane changes are minimal and curves are gentle.
The hard parts of driving (aka not highways) are the real problem, as expected. We solved the easy parts in 2000 and who knows if we'll solve the hard parts by 2050.
You know what would be really nice? Something that detects when it's safe and reasonable to suggest turning on adaptive cruise control so I use it more. Maybe something like detecting I've driven a few miles at a consistent rate of speed above a certain threshold.
The hard parts are definitely the problem, but there are lots of easy wins left on the table too.
I definitely hope your car doesn't put it in some hidden menus on the central screen.
The hard parts are the whole point of autonomy.. the parts so hard that humans still fuck up and kill people. that's the ideal of autonomy imo and short of that its missing the point.
