This is a training defect which I see quite often, too. It appeared about two software versions back. The left turn lane should be ignored while the vehicle travels straight on. Most of this time, this is the behavior. However, if there is a vertical curve or horizontal curve in the vicinity of...

It took a trip to the service center, and replace one of the repeaters. Now works great. While doing the inspection, they found a crack in the rim of the left front wheel. So probably all for the best. The no-confirmation NOA works pretty well, but occasionally does something really silly. The...

Wow, what a saga. Hmmm ... 1) Seems like replacing the camera didn't fix it. 2) Whatever else he did, did fix it. 3) Let me know if the error comes back with 8.4 ? I'll call our local service center tomorrow, and see what they come up with. Thanks for the feedback.

Any luck in getting the problem fixed? The first service appointment available for me is next week...

Hmmm -- July 2017. The first available service appointment is next week...

It seems like the 2019.8.3 version has widespread problems on AP2.0 vehicles -- it displays the "camera visibility limited" message, and lane change, blindspot, and NOA don't work. Does anyone (including Tesla) have a solution to this problem?

I have the identical problem with my S P100D AP2.0 -- seems like quite a widespread problem on AP2.0 cars. Most importantly, has anyone, including Tesla, figured out a solution to this problem?

I have used NOA a number of times (4 or 5 times) in the Atlanta area, driving from up north to the airport down south over the I85, I75, and 400 interstate system, and back. V2018.42.2. It has worked faultlessly for me -- appropriate lane changes; appropriate exits; nothing scary. Perhaps I'm...

AP2 V20018.42.2 - Autopilot dead as a door nail. Reports "Cruise not available" when you attempt to engage Autopilot. Tesla says they are working on it... No timeline

Let's support the bold and the doers - I'm impressed with V9 even though it is a bit rough around the edges..

I noticed yesterday for the first time a slow down on a back road on AP when aproaching a stop sign at a T junction. I commented at the the time "wow, did you see that" to the others in the car, but did not go back to retest. Not sure if it was the T junction or the stop sign... V2018.24

I don't mind the nags - just keep your hand draped on the wheel and the nags are not irritating at all. However, the big problem for me is that 2018.21.9 is a BIG step backwards in terms of jumpy and nervous behavior on roads that it previously drove very well. It swerves down side lanes and...

Thanks for the visit @benfar .Interesting conversation and drive, with a few edge cases that proved quite interesting: 1) a missed detection of a weird trailer carrying a car, stopped at a traffic light as we approached from behind. The system just missed this one completely. It is 50/50...

Drove 200 miles today in North Georgia with 2018.10.4 on winding rural roads with plenty of crests, dips, poorly marked roads etc. It is a route I've regularly driven with AP1 and prior versions of AP2. Well, hats off to@Tesla for this version. It really is a significant step forward, and makes...

Yeah, you will not regret it. I can't imagine driving without AP, even with the current limitations. I received 2018.10.4 and on my drive today (about 150 miles) the lane keeping; slow down for curves; and detecting stopped vehicles ahead were all substantially improved.

Occam's Razor. The simplest explanation is: 1) Tesla is working from EAP -> FSD. Their test drivers sit behind the wheel, with hands on 'testing EAP'. 2) The others are all starting at FSD 3) Tesla lawyers interpret the requirement from CA as only applicable to FSD 4) Tesla layers say 'no...

I think the expression is 'truthful hyperbole' which has been used by another well-known American prone to exaggeration to make a point...

There are two separate issues here: 1) FSD or autonomous driving - a year or two away - still has a driver in pilot/copilot arrangement, and maybe save some of the 40,000 lives lost on the road in the USA each year. This is low hanging fruit that is within reach. 2) Driverless cars. This is the...

Humans drive with two cameras and a super computer, with AI and deep learning. So why, in principle, should a self driving car axiomatically need lidar, when humans don't?

Do you have a reference for this quote? I recall he said that 'freeway driving was basically a solved problem' and that is basically true. The devil is in the details in the quotes...

It's a common problem in the software business: 1) Add a new feature, even a really useful one, and everyone is pleased (in very small letters) 2) Remove a feature, even a small one, and everyone is PISSED (in very big letters)! The auto wiper feature worked very well in AP1, and now that I've...

Actually, they are pretty funny! Take it easy, this is a site for enthusiasts, not a forum for proving who is right, and who is wrong. We are all disappointed in the progress on FSD and AP2 this year. We are all hopeful that EAP and FSD are around the corner. We all agree that incremental...

ON. It reduces the number of times your foot needs to change between the brake and accelerator pedal. This is less tiring, and less prone to error, than OFF

I think it takes about 1,000 miles of driving to become fully comfortable with AP. I have 20,000 miles on AP1, and now 10,000 miles on AP2. Once you get used to driving WITH AP as pilot/co-pilot, then you'll never go back. But this takes much longer than a day - it is a new driving experience...

I take your point, 'parity' will always be a bit subjective. However, 2017.36 (in the last two weeks) has seen a big improvement in all the irritating things that made AP2 deficient. The diving for exits may still be an issue, as I compensated for that some time back by driving in the middle...

I have a MS P100D, and about 8,000 miles on AP2. I previously had a MS 90D, and did 21,000 miles on AP1. My view is this: 1) AP2 has finally reached parity with AP1. I use AP2 now in traffic; on divided urban roads; on small rural roads as well as freeway. It works really well now. 2) The...

Yep, I also experienced AP2 hugging the right hand side of the lane, at slow speed. Very close to a truck on the right hand side, and so I had to center the car by hand. Seemed to only happen at slow speed.

Yep, definitely a problem. My AP2 sees black tar lines as lane dividers. It also sees the joint between two sections of asphalt as a lane dividing marker. My expectation is that this will continue to improve in future software releases, as more data trains the system. However, the latest release...

I traded in my S90D AP1 for a new S P100D with AP2. Only 4,000 miles on the new car, and so far, so good. No signs of Truck Lust on AP2 so far, and I have done a number of long trips. So maybe Truck Lust is only an AP1 phenomenon? By the way, love the new car. AP2 is now finally at parity with...

I have traded in my S90D (AP1) for a S P100D (AP2) a couple of weeks ago. Pretty interesting to see the difference in 'personality' between the two AP systems. Still not sure whether I prefer AP1 or AP2, as there are quite a few things that AP1 does that AP2 still does not do. However, this week...

When the 'Truck Lust' occurs that we are talking about experiencing, the lane markers disappear in the dash display. The effects that you observe are also real, but are not the effect that we are trying to pin down here. However, by completing a 2,000 mile road trip without the sudden...

Can you check next time you experience this 1) Was there a shadow between you and the truck? (one theory is that Truck Lust does not happen at night - it needs a shadow) 2) Was the truck white? (one theory is that it happens with white trucks)

it seems likely that the object detection, including lane line detection, is done in the Mobileye processor. Hence improving the performance around trucks may not be under Tesla control, but tighter integration by Tesla with the radar may be possible, to lesson the effect. And in support of the...

This is a great analysis! Thanks so much for putting in this effort, and your detailed work on the subject. I can add the following based on my own drive down I 85/I 285 in Atlanta today. I had someone else drive, so I could watch in detail as we passed plenty of trucks on this interstate. I can...

Nice! Perfect video of the 'truck lust' phenomenon. I watched the video several times. Look carefully at the behavior of the blue lane lines on the dash camera while coming up behind the truck. The blue lane indicators disappear, and wobble, as the truck (and it's very strong shadow) come up to...

My software is 8.0.2.50.114. I'll see if the 'truck lust' improves with the update, when I get it (hopefully soon!) The truck lust experiences from Thursday were during good weather, during the day, with sunny/overcast conditions.

My suspicion is a longitudinal shadow created by an 18 wheeler sometimes 'looks' like a line (hence the wobble). Perhaps shadows created by the bridge railings had a similar effect? Then other times, when the sun is in a different direction then no effect? Just speculating that your observation...

I was with 3 other engineers in the car during this drive, and so we were all trying to observe/figure out what caused it. We did speculate on air buffer/cross winds having an effect. However, on this drive there was no wind (the trees were still) and we couldn't think how the aerodynamic...

Yesterday I did a 500 mile round trip from Atlanta to Alabama and back. 95% of the time on Autopilot (AP1) and it worked great. Most of the time while passing trucks, no problem. However, at least 4-5 times on the trip the AP would start to wobble, and veer from side to side (including towards...

How about this suggestion? We all just use @tesla as a handle for directing comments to Tesla. Sounds like a reasonable 'crowd sourced' way to direct owner input to them. You listening, @tesla?

Yep, the AP1 performance does seem much improved since initial 8.0. It is tough to tell whether it is from the software update, or the HD maps have accumulated (in a mysterious way!) data which improves the experience. One even gets used to the speed limitation; the 50mph limit when passing...

Only when using Autosteer. When using TACC there is no limitation on the speed you can set (up to 90 mph, I think, but would be crazy took set this high on a non-freeway road)

It goes to show the need for PREDICTABILITY in autonomous driving system. We are all experienced AP drivers, and this (and other blog posts) show we are all just trying to understand the behavior, so we are not surprised that the car suddenly does something weird. So we would all be helped by an...

I like your theory. It may be detecting the bridge as an adjacent stopped vehicle, or maybe an artifact on the map. Or also could be part of the 'white listing of overhead radar detected objects' which Tesla said they are doing. We'll see if this improves over time, or whether it is an algorithm...

I also experienced sudden deceleration in the middle of a freeway (GA400 in North Atlanta) today. There were no reasons with regards to road conditions for the behavior. The slow down happened to be while the freeway was passing under a bridge. A minute later the speed reverted to the requested...

Thanks for the lists! There are 816 vehicles on the list. Sounds like a lot, until one considers: 1) There are over 200 Tesla stores. So inventory is about 4 per store. Between vehicles on the floor, and vehicles used to give demos, I would have expected MUCH higher numbers if Tesla had a lot...

Yeah, who knows how they prioritize development. I can't see the downside to Tesla myself. 'Information is data, in context, made useful'. This would be information which would make the Tesla brand stand out even further ahead...

Good discussion. However, before resorting to negative reinforcement ('punishment') like charging for charging to change behavior, let's start off with 'good old information'. I saw at the Tesla factory their display of number of stalls occupied in each SC location. So Tesla have the...

It seems like AP looks up in the navigation database the status of the road. If it is defined in there as a 'major arterial road' then the AP is not limited. If not a major arterial road, then AP limited to the speed limit. However, the database with this info is buggy. In suburban Atlanta, the...

It would be nice to get an email from Tesla as follows: 'Dear valued Tesla customer and Autopilot user, We have made a change to the speed restriction of Autopilot on 'in-town' roads, where Autopilot is now restricted to the speed limit, instead of the previous 5mph over the speed limit. We...
