My FSD challenges so far

[shahfarh]

Three major issues that makes me disengage more often - hoping there are solutions soon:

• Turning into oncoming traffic: While exiting my neighborhood and making a left turn, the system has twice entered the lane of oncoming traffic. After this repeated issue, I’ve lost confidence in its ability to safely navigate this turn.
• Sudden braking at roundabouts: The FSD either brakes abruptly inside the roundabouts or fails to account for vehicles already within them, creating potential safety risks and disrupting smooth traffic flow.
• Failing to avoid road debris: The truck drives over road debris instead of safely changing lanes to avoid it, which could lead to damage or unsafe driving conditions.

I have an intersection that I commonly travel through that is a dead-end into a US highway, on top of a hill, so vision is lousy for normal drivers. The vehicle handles it fine. You just got to get used to it.

Been through dozens of roundabouts with no issues.

Road debris avoidance really isn't in the codebase yet, although it seems to be doing some of it.

Me driving: gets constant lane-departure warnings for riding the lane lines
FSD driving: does the exact thing I kept getting warnings for

FSD on the HWY is too slow, it doesn't want to drive to the max speed I set. Its comfortable around 65-70 but if the left lane is driving at 80 we have to keep up. Only way to hurry it along is with accelerator pedal.

I was frustrated with the slow highway speed, but relieved at least after giving it the accelerator "encouragement" to speed up to setpoint it seems to maintain, at least for awhile.

I got FSD while visiting relatives in Denver, then used it to drive back to Texas. Here's what I found:
It does a poor job of reading speed limit signs, mostly for high speed limits, but occasionally for going from high to slower speeds. That led to having to set the speed limits manually and a seeming reluctance for FSD to speed up. It had no problem slowing down, which it did immediately after passing the lower speed sign, to the chagrin of anyone following.

There were many oversized loads on the Texas back roads. FSD seemed unwilling to give wider berth so I did. In Denver, a pickup veered into my lane and the CT failed to react. The pickup retreated when I hit the CT's horn.

The CT doesn't avoid road debris. Colorado and Texas roads have lots of shredded semi retreads, which can cause damage to any car that runs over them, as evidenced by multiple cars stopped with flat tires. On Texas back roads, roadkill is common. The CT didn't care if it ran over a dead skunk, but I did. It was relatively easy to avoid.

Navigation does a great job of trip planning so that Superchargers are well placed, but it doesn't seem capable of backing into the charger. In fact, it alerts that you're too close well before the cable can reach the truck's charge port.

While FSD is close, it's not there yet. Sometimes it's too aggressive and sometimes it's too timid; either situation is dangerous for the occupants.

Speed signs are a little problem right now. The Automatic Max Speed is relatively new and is also a little problematic at times.

It doesn't really avoid road debris, but there are some situations in which it does appear to do so.

The vehicle absolutely moves over for wide loads, it even does so for regular 18 wheelers. It's subtle when it does it, but you can see it shift its position in the lane when a truck comes by.

In general, since it was new to you, you didn't trust it. It will takes weeks or months to trust and start to understand it. To a great extent, new users will disengage FSD a long time before FSD ever gets the chance to react.

I live in a gated community. FSD doesn't yet recognize that we have to stop and wait for gate arm to go up. I also think it waits a little too long to start braking for stopped car in front. But other than those 2 things, it's been working for me as expected for first CT version.

I am enjoying FSD on my Cybertruck so far. Some things I believe they need to address are that most people are not talking about:

1. Tailgating - The Cybertruck on the freeway can get itself in situations where it is following an an unsafe distance at 65 mph. It needs to allow the driver to select the "distance to follow" or FSD profiles. When it is tailgating and two cars ahead begin to slow, the Cybertruck does not react. It doesn't react until the car in front of it starts to slow. So if they are late on the breaks when traffic comes to stop on the freeway, then the Cybertruck will have to break aggressively. At 6,600+ pounds, math starts to play a factor in slowing down that much weight. The chances of it stopping are on the lower end and on the more risky end of the spectrum. It has stopped every time. The bigger worry is the person behind me and their ability to stop in time. What happens when it rains? Is it still going to tailgate?
2. Late Signaling - The FSD gets itself into situations it doesn't need to be in by not getting over soon enough. I notice it is pretty consistent on the freeway exit by my house. Between 0.4 and 0.5 miles it will begin moving over. If there is not traffic that is fine, but in the Bay Area and you are in the #1 lane and you have to cross 4 lanes to get to the exit 0.4 miles is a short runway. It should know to work its way over sooner. I find myself signaling to force it over when I think it should.
3. Stops & Go's - At stop signs or stop lights I feel the regen breaking needs to be using more than the breaks. When I am stopping using regen my stops are butter smooth. There is no jerk at the end...if that makes sense. A computer should be able to do that. When it is time to go, the initial hit of the "accelerator" by FSD is a little to harsh. You feel the acceleration, then it backs off. Why? Why not have more of a linear acceleration curve to get to the desired speed. This also could be addresses by driving profiles. With that being said, I drove a Model 3 loaner than had FSD and in "Chill Mode" it still would have that harder acceleration.

Every one of those sounds like drivers I know.

That's what FSD gets when it learns from people!

I am using FSD for >80% of my driving now, I really like it.

Issues I have seen in my experience :

• Every leg of my trip requires at least 1 disengagement.
  • 70% minor, like I don't like the nav its taking, or slowing down to a crawl confused.
  • 30% major. Situations I feel would result in damage to the CT or an accident/ticket.
• Braking can be too harsh at times.
• On one intersection near me, the CT will go into the outside left turn lane, even if I start on the inside left turn lane. This happens in the middle of the turn, cutting off people in the outside lane.
• I found out the reliance on FSD actually made the urge to sleep at the wheel stronger than when I drive without it. This is hugely countered by FSD not crashing after I closed my eyes. Don't worry I pulled off the highway and got caffeine after that scare, no issues the rest of the drive.

Unexpected benefits:

• FSD is more efficient than I am. Normally resulting in a 5-15% improvement over my driving style. I believe that mostly comes from reduced speed, but its hard to say.

A small amount of debris on the road over the weekend from Hurricane Milton. No other cars around and it made a left turn into the wrong lane and then essentially stopped. Thankfully no traffic at the time

Still can't figure out why. I let it play out because no cars around. It was in broad daylight with pinestraw on the road that I guess mayy have covered the painted lines but still....shouldn't happen.

Overall since small bug update the merging to exit the highway is better. Lefts are still too tight.

 

[DJAlan2000]

For us, it's the following:

1) Turns too tight when making left turns... Hasn't actually hit anything/anyone, but it sure comes close... Had one person 'honk' at us for it...

2) Rides the left line on the lane... Even riding over the reflectors for quite a way... I think the 'centering' needs to be moved over about 6-8 inches... That might also fix problem #1...

3) Speed doesn't stay consistent... If I am on the freeway (Speed limit 65) with no traffic, if I speed up to, say, 75 and start FSD, within about 1 minute the speed has dropped to about 72 mph... Then, within another minute I am at or around 65... If I don't do anything about it, it will slow down to 60 mph (below speed limit)... Not a good thing if you have to keep speeding up all the time...

4) When coming up to a traffic jam (on highway), it comes in HOT... I have even tried 'lowering' the set speed from, say, 70mph down to 55mph when I see traffic ahead... But it doesn't slow down very fast (my model Y is much better!) or very early... Then, it looks like it's going to hit the car that's stopped in front of me... It doesn't (or hasn't yet!), but scares the heck out of me and my wife when it does that! Does it even in 'Chill' mode...

5) Did I mention that it likes to ride the left line in the lane sometimes? Oh yeah, I guess I did... But hey, that's important to fix!!

I have been using FSD for a week now about 95% of the time. My list includes:

1. The auto speed is rather annoying. I am constantly on the accelerator to rev it back up to 7 over. It is especially annoying on turns as it actively slows down during turns and it is so much worse than just maintaining the speed or accelerating through the turn. Question: If I set the speed to the other option instead of auto, could I just control speed with the right scroll wheel like cruise control?
2. The system absolutely CANNOT detect things on the ground. I ran over a possum the other night. It also was going to drive straight over some branches. It also doesn't detect speed bumps and will take them at a higher-than-expected speed.
3. Roundabouts are a bit unpredictable. The first 3 times I went through roundabouts it rode up on the inside shoulder a bit and I disengaged. Now, it'll take those same roundabouts. If there's no cars coming around it's great. If there are cars that are coming and the computer is not sure if they are going to turn off or continue around the bend it with jerk to a stop and start for a bit.
4. The active driver monitoring keeps on disengaging and forces me to be apply for to the steering wheel.
5. Sometimes it doesn't get over when it needs to. It's more of an issue of not knowing the local roads. I don't really find this an issue as I can engage a turn signal to force it over sooner.

Turning into traffic has been great. Navigating heavy traffic is an absolute dream. It is REALLY polished and I plan on continuing to use it.

I think with auto speed it's driving the speed that it thinks it should be driving in the situation. It is slow to get up to speed sometimes for me and not perfect. But for the most part, I have been happy with it. I look at it as I'm a passenger and not the driver. If I was just riding in the back I wouldn't care if the car was doing the speed limit or 10 over the speed limit. If I want to speed then I'll just do the driving myself. I think people are going to have to adjust to it. It's not going to drive like you do.

I took a 240 mile round trip on Saturday and never had to disengage it. Mostly it was freeway driving. A couple times it did overstay it's welcome in the left lane. But overall I was very pleased. Being able to do a long trip like that without touching the wheel or pedals is pretty amazing.
