Where I grew up, it was dense snow, which behaves pretty similarly. I don't really see the value of saying "human error, so who cares about solving it with tech!" It's human error that happens all the time, and causes plenty of injuries and expense. Falling off a cliff is human error, but we still put up railings where it's likely to happen. And as you pointed out, it's not human error that a single driver can solve - if you go slow enough to be safe, you're likely to get hit from behind by someone who didn't. Since the reality is that drivers are faced with having no safe strategy, it's a problem I'd love to see solved.
