Yeah I have never heard this mentioned by Tesla, but myself I have thought about that from time to time. If my lane is clear or becomes clear, and my speed is set to 70, but the other lanes are going 25...ummm...you don't go 70. So I think the concept makes sense, and it's advancing a little more towards FSD. I am wondering how well it's going to perform in "real life". Because I've got autosteer swerving within my lane for trucks that are one and two lanes away. Seems like we might have an increase in unnecessary deceleration events, at least for a little while.
