I commute regularly on the US101 from San Francisco to Mountain View. I second brianpan that the car doesn't need to move over, and predictable stable behavior is more valuable. However, I do notice that Teslas drive more in the middle of the lane. I have no idea if that's automatic driving, or just a coincidence. Motorcyclists generally try to lane-split between the two lanes furthest to the left - because cars on the leftmost lane tend to stay closer to the left side of the lane (because there are no cars there), which creates a larger space. So if anything, it'd be nice if Tesla automatically stayed a little on the outside of the lane when it has either of the end lanes and there is a good shoulder.
