When I use FSD to navigate to my house there's a bug when I arrive that causes the vehicle to continue driving with no location set. The vehicle pulls up on the street in front of my house and says that the route is complete. The steering wheel turns partly to the left. Then when I press the end trip button it starts to drive on its own. It has no location set so I don't know where it's going. It safely follows all driving laws. Although it doesn't follow a specific route it does follow a few rules. When it reaches an intersection, it prefers to go straight. If it can't go straight, it goes right. If it can't go straight or right, it goes left. It will continue to do this until I cancel FSD. Has anyone else experienced this?

FSD Driving with no Location Set

I've seen YouTubers try this many times on many versions of FSD. The car will just keep driving as you say. It doesn't need to have a location to use FSD.
I wonder if you come to an intersection that has right, left and straight options if you turn on the left signal if it will then go left?? I'd assume it would. I'll have to try this today.
I did a YouTube video showing hand position to avoid FSD nags, and for that drive I just turned on FSD without a destination. It gave me a nice tour of the area, making turns on its own. As you say, it only made right turns, but I got at least one turn to the right when the car could have gone straight. The result of that right turn was to go into a cul-de-sac, come back out and take another right, allowing it to continue straight on the original road. I'm assuming that map data has a role in whether it goes straight or turns.
I use FSD without a destination all the time. It works like a high functioning cruise control, including lane changes when I signal (Minimal Lane Changes is de rigeur). I tend to use it when I'm on a road for multiple miles.
I can confirm that the current version of FSD doesn't follow input from the turn signal. If I use the turn signal FSD ignores it and either drives straight or makes the turn it intended to turn.
Some say if you hold the turn signal down it will observe it. I keep forgetting to try it out.

Yes, that is the exact scenario I described in another post. I refer to it as an "Unexpected Behavior". It is 100% reproducible and the second time it happened I just let it drive by itself for a while to see where it would go. After about 7 miles, I disengaged FSD and went back home. Don't know where it thought it was going.
Replying to my own post...
I was able to try this out on two intersections. First one FSD (without any destination set) came to an intersection where one must turn right or left. It put on the R signal. I held down the L signal and it switched and turned left. Next intersection it was planning to continue straight. I held down the R signal and it turned R. So it seems this does work.
I thought I had turned off FSD, but it turned out I hadn't. Sometimes I Ilike to use the Cruise Control and the stopping at stop signs, and red lights. So, I didn't set a navigation point, just took off. But I could feel how rigid the strewing was . Once I got to a corner I put the left turn signal on--but the car refused to turn left.So I took over.
It turns out, you need to check what your identity is--if you choose to use or not the FSD.
Same here. In our tests FSD with no destination performs as if it will continue on the current road going straight indefinately. when it gets to a terminus, it invariably takes a right turn and continues on that road, apparently until another terminous. we are trying to find a route where more than 1 terminous exists to prove it will continue this pattern, but we assume it will. using this logic, you could potentially get on an east-west road and drive to the ocean without a destination (software-wise). your experience in a neighborhood with the right turn when it could have gone straight was likly a camera visibility issue, essentially the software wasn't sure it could go straight and so it turned. we believe without a destination, FSD is not using GPS reference data to its full capability.
Nah. Perfect visibility. There was no reason to take that right, which is why I attributed it to map data. As I recall, the road was gently curving to the left at that point, so it may have decided that a safe right was better than any left at all. The map data is organized into segments, so it may have considered the straight a left turn.
I think you nailed it - the road was gently curving to the left. FSD is overreliant on the cameras. even when the GPS says the road continues, if FSD can't clearly see that, it goes for option #2, particularly without a route in the nav. the reverse is true also, which is why FSD has been known to continue down a dead end road, even though the map clearly shows it ends on the screen. we've also had it get confused with the sun in its eyes, just like a human driver. LOL
It's a tough balancing act though. Map data is updated on our cars once or twice a year, so if new construction or lane shifting occurs outside the map updates, the car could be operating on bad GPS/map data.
You may be thinking about the visual map data you see on the screen. This is streamed from Google. The map for navigation is downloaded to the car from another source (there's debate on what this source is). This is the reason you may be out of cell range, so the map on screen is blank, but you can still maintain the navigation route you initiated prior to losing signal.
