about FSD left turn or parking

[yjb521]

My CT's autopilot often makes mistakes when turning left. For example, when there are two left-turn lanes, it will turn directly from the rightmost left-turn lane to the left left-turn lane, often causing vehicles turning left in parallel to almost collide. It also turns directly to the opposite lane and even turns on the line. This happens many times when turning left. I am helpless. Another thing is that when parking uphill, it can't even recognize the obstacles in the parking space ahead, especially when the obstacles are less than 1 foot high, and it will directly hit them. . . . . .

Yes. This version of FSD is SUPERVISED. You need to intervene when it makes these mistakes and report them, so that the system learns when it makes mistakes. It uses a reward/punishment system. The reward is it making a decision and being allowed to complete it, the punishment is a disengagement.

I have had the same xperience with double turning lanes - which are common in Texas - whether turning left or right. The truck will drift during the turn from one lane into another (most commonly from the outer turning lane into the inner turning lane). The double turning lanes are marked on the road - a sweeping dotted line arc - but that doesn't seem to matter.

Even if you're supervising, during the timeframe of a turn (say 5 seconds), you might get 1 to 0.5 seconds of warning that the FSD is drifing into the other lane. The reason this matters is that even with someone in the inner lane, FSD will cut across if there is sufficient gap (maybe 1 car length). The best method to correct is to use the wheel to force the truck back into the correct lane - which takes another second. The end result is that the truck looks it is being driven by someone who can't follow even the most basic rules of junctions. It is not crashing into anyone, but it is giving people a fright because it is doing something unexpected at exactly the moment when all the other cars are well-behaved.

I have multiple double turning lanes on my commute so have experienced this dozens of times, and FSD has been consistently bad. Now I just disengage FSD at these turns and reengage once the corner is completed.

My mental model for FSD is not that I'm surpervising, but rather I'm a driving instructor and the student - while they have mastered not crashing into people - seems to be unable to follow basic road protocol in any even slightly complex setting (double turning lanes).

My expectation is that FSD should be able to drive and handle situations as well as we expect everyone else on the road to and with the same decorum (humans or otherwise).

Ive noticed the same thing, theres a turn near my house like this. Not only that but after you make the left turn, the left lane becomes “left turn only” and by the time the truck realizes that, it is already in the left lane and needs to quickly try to get back into the right lane. I think with frequent reporting and disengagements around this type of turn, the ai or engineers will realize what is happening and a fix will be applied.

in v12, i had a model Y that would come to a stop at intersections with flashing yellow lights before making a left turn at night, looking at the screen, the ai saw them as flashing red. If i tried to hold the gas through the turn it would freak out and say take over. It no longer does this but sometimes still requires prompting that its ok to go… FSD is a work in progress for sure.

Yeah. Not sure what the left hand turn hangup is but it’s definitely scary when you cut across a lane with oncoming traffic in it.

Are you doing the voice notification each time you turn FSD off?

 

[TesLorean]

I did do voice notifications the first dozen times. Pretty sure it caught a few "sh!t". I don't mind reporting problems - but lets think about this. You are in the process of correcting the FSD from doinog something it shouldn't - about to cause a traffic incident - and thus recording a message to the developers is top of mind?

Double turning lanes in Texas do not involve crossing into on-coming traffic. Two lanes heading in the same direction are turning left (or right) in "parallel" to each-other.

I just want to say that I'm very unhappy recently. The FSD's turning has hurt my CT. What are their engineers doing? Is it because of the stock market crash? Don't they have the heart to work? ... I don't want any serious accident to happen one day because of a left turn problem. ... How can we make people pay attention to it?

You must be new to FSD. It's always been two steps forward one step back. The turning lane thing is a big problem, and it will be resolved, just in time for something else to pop up. It is improving, just looking back at 2023 it's made HUGE progress, but it's not linear.

I remember when you couldn't adjust the speed on some highways. Very glad that's been resolved for a long time.

I have driven 20,000 miles. Regarding this issue, I feel that the CT relies on the visual system to determine the driving route, which should be caused by visual blind spots. There may be design flaws, so I raised this question!
