I regularly ride down I-40 and back in North Carolina in my Rivian. I don't touch the wheel from the moment I get on the highway until the moment I get off, pretty much, unless I decide to take a rest stop. The universal hands free is as good or better than what my old Tesla had, and it'll get updates while a 2019 Model 3 almost certainly won't.

On the other hand, when I got FSD trials in the model 3 in the last year or so, it never managed to get more than ~a mile without me having to disengage.
