They are very useful. Augmented situational awareness is clearly valuable in a high-risk relatively-low-tolerance environment like driving at highway speeds

I also really don't want to be sharing a road (or parking lot) with cars that lack most of those features.

Heh, ok. Never had a car with those features, and I've never been in an accident. I even drove professionally for some years before such features were available.

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.

I find I'm even more aware of my surroundings when I drive with these safety features.

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.

So when you don't have to pay attention to speed and position of cars around you then you can spend more time predicting other motorists?

What are you basing your predictions on if you don't even know the distance to the one in front of you?

He doesn't have to pay attention to actively controlling speed and distance to car in front of him.

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.

I'm sure there are plenty of statistics available out there. Unlike many believe you can't determine reality by posting to social media.

I used to have a similar perspective. Then one day on the highway, a quarter inch of snow started to fall. Traffic slowed to 25mph. I was driving arrow-straight at 25mph on decent tires & flat ground - and suddenly my pickup just started to spin. Traction control immediately kicked in & fixed it.

To be fair, the weather's a bit wild here. But now I don't mind having traction control so much.
