UHF Universal Hands-Free decided to switch lanes

[SLVRon]

I installed the 2025.46.0 update a couple of days ago, and I've been trying out Universal Hands Free. Today I tried it on a section of road knowing that I'd be ready to take over when I reached a traffic light ahead. The road layout has recently changed at that light, with a new left turn lane added. As I approached the junction my R1S decided to move to the left turn lane even through I hadn't indicated I wanted to do that. The light was green, but I did have to grab the wheel and pull it back to the correct lane. Not sure if this has anything to do with that particular intersection not appearing in Google Maps yet, but this is one for you all to be aware of if you're trying this out in a similar lane setup.

Google street view currently shows this, and I've tried to show what the junction looks like now. The green arrow is the direction of travel I expected to follow, and for some reason Universal Hands Free moved me to the left turn (white arrow) lane.

There have been a couple of reports of UHF choosing the left-hand turn lane or the right-hand turn lane in situations like this where it's perhaps ambiguous which one is the "straight" lane. From your drawing it appears that the left-hand turn lane more closely aligns with "straight", and you would have to jog to the right to obey the lane markings.

UHF is still learning. I expect it will get better at this sort of thing. But I don't think there was any danger that the vehicle was going to turn left, it just made a mistake as to which lane was for through traffic. I make that same mistake sometimes when I can't see the markings from far enough away or due to weather/time of day/etc.

It'll be a long while until you can really trust this system., pay attention and keep letting it learn.

This is just what UHF currently does. In my case it sees the center lane line, but loses sight of the left line (turn lane). Wanders left to find it, then moves back into the lane after it sees it. Sometimes over corrects getting back into the lane. Worse at night when the left line is more difficult to see. UHF does this on highways too with on and off ramps. It wanders over trying to find the right edge line. Both are very annoying. Tesla FSD had the same problem on highways years ago. Have since fixed it.

I have had this happen, both to a left lane and to a right lane. My take is the system prioritized the solid line over the dashed line and moved towards the corresponding solid line, left or right.
