I've been thinking about this ...
How does FSD improve disengagements ? Obviously by making fewer mistakes .... but how does the driver know whether a mistake is going to happen or not ? What we do is - guess. The guess is based on several factors - some can be easily characterized, like we think given the speeds and trajectories of all actors on the road, an accident might happen. Or we see that FSD is very indecisive ... jittery. But it all remains .... a guesswork. May be my guess has been faulty i.e. I've been disengaging when there wasn't a need. Afterall Omar disengages quite a bit less (and AFAIK) hasn't had any accidents. So, his guess is actually better than mine ?
In other words, one way disengagement rate goes down is when the testers feel less threatened. FSD can improve disengagement rate by gaining more trust.
Looks to me that is exactly what has happened. FSDb has gained a bit more trust from me. So, though it feels like I "lowered" my standard, in reality disengagement rate went down because it gained more trust.
Now, did FSDb gain trust by improving in some ways ? I do think so ... but I don't expect my trust level to be linearly correlated to actual FSDb ability. Its probably a step function ...
EV now I would agree with your statement above. I must be a little more trusting of FSD. Probably because I leave for work real early in the AM and mostly have the road to myself. I can let it do its thing. I do have my hands on the wheel when trying new actions or movements. Then when I'm in PM rush hour I'm not so nervous and ready to take over in a heart beat.
I do get surprises when the car screws up on things it has done before flawlessly. 69.2.3 has been the worse release to date in my opinion. I'm used to improvements not regressions. I this version I was surprised with several regressions and possibly on first runs of the route only to improve with repeated trips. I constantly run to work without any disengagements because I typically don't have to look out for the other guy, and can let it screw up. I have the same turn lane I have to play with the signal stalk to over ride but that is it. I believe Tesla is activating NN functions with each release and that's where the trouble began.
I had repeatedly gone through toll booths without issues. 69.2.3 comes out and the car is now following the white line trying to center when it missed the large stationary toll booth dead ahead. I was going to hit it dead on before disengaging at the last second. Has NN been given priority over fixed images in the library or what ever you call it? After that first trip the car has continued to do the same trip fine through the plaza then goes on it white line to the right hugging maneuver. I do typically get the " tool booth detected" pop up. I don't know if the map missed it on my first trip. Rising sun blinding cameras?
A new issue is multiple turn lanes. My car is no longer staying in its lane and I don't let it waver to much. I almost plowed into the side of the adjacent car and disengaged. I believe it is because they have increased turning speeds. As EV now noted, I have a low tolerance in this type of turn which is frequent. A lot of my disengagements have happened in these types of turns. I'm holding real tight ready to take over and the car thinks I want to.
I have a nasty 45MPH to 55MPH a tight right turn on red that I deal with every morning. No exit and or merge lane. I can have a wall of cars coming or nothing. One morning I had a wall of cars coming and very close to me, and the car went for it after creeping out. I slammed on the brakes and stopped. It had been doing this properly. This was a total surprise but I was ready. Its real fun to do when the light is green. I don't know if were going around at 15 or 45 MPH, they need to tune the speed when turning.
The last surprise I got was sitting at a signal on red. the turn lane signal went to a flashing yellow and we were red. The car just drove off like the light was green, but it was red. No sun light issue either. It flat screwed up and drove right towards opposing traffic turning left.
So after all these trying events I feel the system took a step backwards, and I lost some trust. I still use it daily thought. I have been running it for almost 30K miles.
Funny side note on how used to FSD I am. I went to Indy last weekend and had a brand new 2022 rental car and had to use Waze and Drive the car, I didn't know the area at all. I had to focus and listen to Waze, and drive the car! man o man I'm not used to such antiquated machinery. my driving skills have really dropped off. I couldn't even get used to the gas and brake pedals for the first day. The wife is bitching at me to drive normal, reverse case to FSD complaints. What can I say, I have been driving one pedal electric for nine years now. I didn't know you HAD to use the brake pedal.
