When I don't have to pay as much attention to my speed, distance to the car in front, etc I get to spend more time predicting what my fellow motorists are about to do in ways I know my car isn't able to easily compensate for.
What are you basing your predictions on if you don't even know the distance to the one in front of you?
It's really obvious which of the commenters in this thread haven't used a car with ADAS (like you). I don't mean that offensively. All the people here saying that ADAS makes driving safer aren't delusional idiots. As the HN rule says, perhaps we should accept others' opinions in good faith rather than shitting on tech we've never used.
To be fair, the weather's a bit wild here. But now I don't mind having traction control so much.
I do wonder whether those features train people to not be able to check a blind spot by turning their head, or just being more generally aware of their surroundings on a highway.
