Disappointing that AP didn't avoid that. The Honda came over pretty slowly, AND, there was an open lane to the right.
I'm not sure the AP could avoid riding in the blindspot, since it was following a truck. The only thing it could have done was to slow a bit, increase the follow distance, and back out of the blind spot, but the average driver probably would be wondering what the heck is AP doing? Personally, I'd be adjusting the follow distance to avoid riding in someone's blindspot, but that's just my habit.
As for the vehicles not having a blindspot, I always adjust my mirrors properly to eliminate those, BUT, the Model 3's mirrors don't turn far enough away for me to completely eliminate it. It's the first car I've owned in almost 40 years that I haven't been able to get the mirrors to turn far enough away. Strange, they seem to be at their physical limit. May have to get a little stick-on mirror to compensate. Never had to do that before.
