@inthehands @thatandromeda oh, absolutely. I have Subaru EyeSight and it's really good. It reduces fatigue on long drives in ways standard cruise control can't, and keeps a reliable, safe distance.
Although, I've regularly driven the system in two cars, 4 years difference in age, and it's interesting how they've tuned it differently. Where I'm used to it doing one thing in one car, it's subtly different in the other. "Same" system. Doesn't bode well for complete automation.
