Like the “mostly self driving” car systems where the driver is expected to pay attention well enough to take over if needed
Definitely slept a bit while doing night passage (alcohol). Would be impossible in a car given how much driver monitoring is out there.
I wouldn't feel safe if I wasn't listening to something that kept me engaged though. I would totally nod off.
I was excited to get adaptive cruise control, but I’ve found I don’t like using it very much. It’s too aggressive with hitting the breaks to maintain the following distance instead of being able to ease off the gas to fall back like a human driver would. Assume some brands are better at this than others, but anyway I didn’t buy a Mazda to not drive it. So I use that only intermittently for long drives as a bit of a break for my right foot.
