Sure - a good freeway is actually a lot more predictable in most circumstances than city driving, so as a problem to solve it's likely a little bit less complicated. What I wonder about is what it feels like as a passenger. I wonder if it would be more or less frightening than being a passenger when my 17 year old is driving.

I use adaptive cruise control a lot, where I rely on the car for keeping a safe distance.

I have a limited version of SuperCruise which means it operates hands-free on freeways but nowhere else. My wife's Equinox EV has the regular version, which operates on a lot of arterials near us and has more capabilities. The first time that the Equinox signaled, changed lanes to pass, signaled, then changed lanes back was shocking.

We moved to a small town and drive a lot more than we used to and I find that having those capabilities really helps relieve the stress.

I will say that I move to the center lane when going through a notorious set of curves on I-5 in Portland because my Bolt doesn't steer as smoothly as I'd like near the concrete barricades. I wanted SuperCruise because it has a fantastic safety record. There are lots of times it's not available but when it is, I have near-total confidence in it.

I took a Waymo that drove on an 'expressway' which had a speed limit of 40mph and it was definitely a different feeling. I did feel a bit scared, at 25mph it feels like a gentle theme park ride, at 40mph it's beyond that and feels dangerous.
