My wife had a model Y (it was totaled when some jackass rear-ended her - kept her and the kids safe, so I'm happy with the way it performed in that accident), and I have a Rivian. Both have "auto-steer" capabilities (Rivian calls it Highway Assist) that are pretty comparable, having driven both. But the big difference is that Tesla let you use it anywhere pretty much - neighborhoods, city streets, etc., whereas Rivian's is locked an only available on controlled access highways with certain limitations (they have to have been mapped by Rivian). It seems like a no-brainer to limit it to situations that it's intended for, and very low hanging fruit.
So of course Tesla is not going to do that, I'm sure it will just be "our cameras are blinded by the sun, so you can't use auto-steer", not "you're driving in a neighborhood, you can't use auto-steer."
