In a previous post (see: My silky smooth 320 mile road trip with almost 100% AP control), I mentioned that several times on my trip I could not use auto lane change. I'd signal and...nothing would happen. But other times it would work fine. All total, I'd say about 65% of the lane changes worked and 35% didn't. By the time I did the return trip documented above, I had at least figured out WHEN it would work or not work. I'm sharing this with you guys in case this is news to anyone. Maybe everyone already knows this though and it is only news to me.
Anyway, I discovered that when the binnacle display shows an adjacent lane, auto lane change will work. When it does not show an adjacent lane, auto lane change will not work. So while on the first leg of the trip, it seemed totally random, in actuality it was deterministic.
In cases where I was on a 3 lane (or wider) stretch of highway, sometimes the display would show a lane only on one side (example, left) but not the other (right). As you can probably guess now, it would allow me to auto-lane change into the left lane but not the right.
While I can understand the logic that if it thinks there is no adjacent lane, it shouldn't stupidly and blindly move into a lane it doesn't think exists (or is oncoming traffic). But my questions to you guys are:
A) Any ideas why the cameras/sensors don't "see" adjacent lanes consistently? This happened in broad daylight on Highway 101...not exactly a seldom travelled road nor poor weather conditions. Plus fleet learning and the video clips and all...I'd think this would be pretty locked down/mapped out, especially on major thoroughfares.
B) Has this always been the case? Or maybe a recently introduced bug/issue in the latest firmware? Anyone else seen this 'forever' or maybe more recently?
Seeing this image, I know I can auto-change lanes (either left or right in this case)
Seeing this image, I know the car will NOT auto-lane change. But you can see there is indeed a lane to the left of me
