Here's my guess. I think the car primarily reads speed limit signs. If there are no posted limit signs it assigns a speed limit based on the road type. For example, my road is private and the Tesla speed limit is 10 mph. It connects to a residential road and the Tesla speed limit is 25 mph. This is with FSD beta. If this is how it works it really should be changed to a crowd source model.
I've made changes to both OSM and google. I have no idea which is used by Tesla. I am concerned about the long time period between updates of the maps that Tesla uses. If the FSD uses both map and visual data for its decision making if only half of the data is current I can see where errors caused by omissions could occur. For example in a previous post I ask the question " If you are following a high profile vehicle (semi) through an intersection and the driver nor the cameras can see the traffic light (red or green) what will the car do?" When I ask this question I made an assumption that may not be true, that is the car knows because of the maps stored in its memory, there is a traffic light there. Because if it does not know from the map it will not know from visual either until it is to late to react. Therefore if Tesla wanted a failsafe system, in this case slowing the car until it confirmed a green light, it should have the most up to dated maps and they should be updated frequently.
No - it picks the speed from map data. The posted limits can override the map data ... if the map data has no speed, it might use some defaults.
Yeah, I can’t imagine taking my hand off the yoke while Beta is on if I had one. It would seem to be way too hard to consistently grab it mid spin to override with a yoke.
You have FSD Beta and can still see your Safety Score? I can’t even after rebooting the Tesla app. (I can of course see it on my other Tesla that didn’t get the Beta.)
I already did this - I wasn't joking - I ended up buying the Robotaxi in Training magnet and a Caution magnet. I also ordered an FSD vinyl like the oval country code stickers so at least other Tesla owners know what is going on.
I have been most worried about the left turns honestly that have an island right at the turn. I will have to upload some video of the peculiar situations it finds itself. It comes really close to hitting the curb but has done well all three days to miss it. On an unmarked road near my office, it takes a left turn by actually cutting through the oncoming lane. But in the other direction, it stops and creeps forward before turning right even without a stop sign. It is as if it thinks there is just one lane. I may check OpenStreetMaps to see if there is some issue with that road, but it should take a much wider left.
I feel like if you have to explain your abbreviations as you make them YBONMT
Is that a public road or a private drive?FSD hates to turn into here:
Maybe because it's slightly raised like a curb. It's like "curb/not-curb/curb/not-curb/curb" and the wheel shakes back and forth violently. Sometimes it just sails past the turn at full speed.
I am able to see my safety score in TeslaFi and I see I have dropped to 98. It looks like I had some additional hard braking when I was running off of AP for a bit. But it is no longer in the app.
My hand leaves the wheel briefly in tight 90 degree intersections as the wheel rather violently spins around.
It's private I guess, maintained by the HOA. The navigation route does say to turn there and FSD will turn into it like 50% of the time so far.
I just let the wheel spin through my loose grip when it spins. Easy to just tighten my grip to override if necessary. Obviously can’t do that with the yoke.
There is a road near me that has a number of changes in its 5+ mile length but starts near my house at 45. The speed icon changes mostly when I pass a speed limit sign. But if I go from a 55mph divided highway at the other end, the icon in the car has 40 mph when the speed is really 35 mph. It does change to 35 when the first sign is passed. Don't know how it is getting the 40 except from a database somewhere. That said, interestingly enough, the next limit about 1 1/2 miles down the road is 40 mph. It completely ignores the slowdown to 25 around some pretty tight turns. I thumbwheel down as I approach those.
