    how does the new end to end FSD work, need a block diagram from of data flow from the fleet to DoJO to an individual's car

    Deep down the NN is as deterministic as your traditional logic (since you can code an NN in any programming language if you want, though for performance reasons they are usually run on custom hardware). The difference is that an NN deals in probabilities, using a complex net of interconnected...

    GPS include supercharge stations

    I'd 2nd that, I do use it and recommend it BUT it is very techie with rather too many dials, as a result it takes some time to master (and the confused UI doesnt help), but if you really want to play "what if..." type things with your plan, its still the best tool (though, as noted, the other...

    There are apps such as A Better Route Planner (web and phone apps) that can do that kind of “plan ahead” stuff

    FSD v12.x (end to end AI)

    No it isnt, it's average case that matter .. cause that's who drive .. average humans. I dont really care if you are superman and have X-ray vision .. other drivers are not. And that's why the car can beat out humans, as I've already noted .. it can choose from (literally) dozens of strategies...

    FSD v12.x (end to end AI)

    It's really nothing to do with reaction time, unless the car is absurdly bad (and, as an aside, there is no way you could possibly tell if you were 100ns faster or slower without some sort of video you could analyze). Humans have 200-300ms reaction times (best case input to response) but HOW...

    FSD v12.x (end to end AI)

    Unlikely. The C++ code, though unwieldy and complex to maintain, is almost certainly much lower in compute load than the NNs. That said, while the stacks hand off control they dont stop running in the backgrounds, so if they can integrate highway driving into the existing city streets NN, then...

    FSD v12.x (end to end AI)

    But many of these things are about thinking outside of the box. Let me throw in an example. The car cant see beyond a truck blocking the road ahead causing a backup (and no mix of LIDAR/RADAR is going to give the car X-ray vision). But there IS another Tesla also stopped just beyond the truck...

    FSD v12.x (end to end AI)

    That is a two way street. There were MANY posts here before FSDb appeared claiming to "prove" that the cameras would not be able to see red lights, or could not see far enough down the road to make even a safe right turn. Then others that said without LIDAR/RADAR the effort was doomed etc etc...

    FSD v12.x (end to end AI)

    That doesn’t match my experience. In fact V12 tends to dither about which one to choose and often ends up taking rightmost lane as much as any other.

    The NEW UI

    Over the years the power bar has got shorter, longer, thinner and thicker more or less randomly .. its bound to change again as soon as they hire the next UI intern.

    The NEW UI

    You clearly were not around for the V11 UI release, which made the font slightly smaller amid HOWLS of anguish from some people on these forums.
  13. drtimhill

    FSD v12.x (end to end AI)

    All AP functions now use TeslaVision (on newer cars anyway) that does have a unified view across all cameras. That’s what V11 did for AP and NoA. V12 essentially replaced the legacy non-NN code above TeslaVision with new NNs though it’s unclear how tied the two stacks are at present.

    Time to disable bluetooth as a key?

    Agreed the trick is to make it hard enough they will look elsewhere for easier pickings. Sad but true.
  15. drtimhill

    Time to disable bluetooth as a key?

    No, you need two devices to make the relay .. one that is left close to the car and the other close to the owners phone. Assuming the owner is close by you can get back to the car before ti relocks. Otherwise yes you need two people, one to get in the car and start it once the door unlocks...

    Time to disable bluetooth as a key?

    My understanding is they leave the car relay on the front wheel, though you are correct two people would make the theft easier.
  17. drtimhill

    Time to disable bluetooth as a key?

    No, it's a work-around ((though a good one). A FIX would allow you to use your phone as the key without risk of this attack.
  18. drtimhill

    Time to disable bluetooth as a key?

    If you are worried, use PIN to drive. The actual hack is a relay attack, which means someone has to get close to YOU with the relayafter they placed a device close to your car .. the relay then acts as an forwarder between your car and phone, making the car think your phone is close by and...

    Supercharger - Federal Way, WA - S 320th St (permit under technical review)

    Seattle coverage is not bad, but the locations tend not to have an many chargers compared (say) to the huge charger on Geary Blvd above the Target.

    FSD v12.x (end to end AI)

    My guess is he means they are downsampling the camera video to the same resolution as HW3 before feeding it to the NNs. This allows them to train/test the NNs ONCE for both H3 and HW4, reducing training time and cost (which is very high).
  21. drtimhill

    FSD v12.x (end to end AI)

    But in fact you DONT want masses of camera resolution. You need as much resolution as required to get the job done properly and then NO MORE. Any more just wastes vast amounts of NN/CPUI power to generate the same result. Given where camera tech is today, Tesla probably chose the cheapest...

    Individually not necessarily. The UPS model was to plan an entire delivery route that naturally used right turns, so the "3 right turns" would each individually reach another delivery location.

    Issues with car connecting automatically when entering the car.

    Do you have the phone keys associated with the driver profiles? Th e traditional phone "pairing" (e.g for mucis playback) is distinct from, and not related to, the lock/unlock etc functions of the car. To have the car automatically choose a driver profile when it unlocks, connect the phone key...

    What car settings are needed for using SuperChargers?

    Don;t overthink this. Basically, keep the battery above 10%, charge for day-to-day use up to 70-80%, and when you're on a long trip charge to 90% or even 100% of you need to. Top up whenever you want. Anything else is either (a) very minor impact or (b) hearsay or rumor.
  26. drtimhill

    What car settings are needed for using SuperChargers?

    This is inaccurate. The SC charge rate is related to the ABSOLUTE charge level of the battery irrespective of charge limit. It APPEARS to relate to the change limit only because most people tend to charge up to the charge level where the SC will indeed slow down. But if you (say) charge from 10%...

    FSD v12.x (end to end AI)

    But others (including myself) have .. so its an issue.
  28. drtimhill

    What car settings are needed for using SuperChargers?

    No, the max charge level is not related to HOW you charge. Regardless of charging method, the max charge has the same impact on battery longevity. Often you WILL end up charging to a higher level at an SC, but that's just because often you use SC's on a long road trip when you want to use the...

    FSD v12.x (end to end AI)

    But that is temporary .. the plan is to transition v11 highway and replace with a V12 highway NN stack also. However, I agree that the car has NOT been trained on parking lots yet so complaints are pointless.

    Luminar’s largest customer: Tesla

    I find the quantity that Tesla have bought interesting. Too many for "just trying out in prototypes" and too few for production. One thing that struck me was Tesla using LIDAR equipped cars to help train the NNs for FSD (camera only). Right now, Tesla get a lot of data from all the testers, BUT...

    Long term parking

    Also turn off Smart Summon Standby (this is important as oddly you CANNOT turn it off from the app) Depending on length of stay and where you park you may want to turn sentry mode on at night (using the app), though set a reminder so you remember to turn if off in the morning.

    Have you tried a reboot? Something is confused about the enabled features (and your might want to let a service tech look at the car too if one is available).

    FSD v12.x (end to end AI)

    But that's what DOES happen. I can think of a dozen stops near me with limit lines that are WAY too far back to give good visibility. So you stop (or at least come vert close to it) and creep up carefully until you can see. As for "what is the point of stopping", well, welcome to the world of...

    First Tesla purchase turning sour.

    That's not the way a maker figures out warranty period. First, there are legal mandates, after that there market pressure to meet or exceed the competition, but the ACTUAL lifetime of a competent rarely comes into it, except when it falls below the warranty period or if there are systemic...

    Interesting if you watch the screen carefully just as the car plows forward the "snake" is shifting back and forth between left and right forks in the road. For some reason the car wasn't able to make its mind up .. I wonder if it would have recovered if he hands intercepted. Though I found it...

    First Tesla purchase turning sour.

    Well there are a LOT of owners on these forums that have cars with that mileage and above. There are other reasons that Tesla limit the warranty other than the car will fail at 100,000 miles (it wont).

    FSD v12.x (end to end AI)

    That's more or less it. There are many parameters for follow distance, including weather, speed, mode etc. The training then is to generate the correct follow distance based on these values, using a dataset that provides the needed mapping. I'm not saying this is what Tesla do, the actual...

    FSD v12.x (end to end AI)

    But it's slightly more complex than that because Tesla are not using (so far as I can tell) semantic versioning. The major version more or less changes on a whim of Elon, so the team makes do with minor/release versions, which means that they may or may sneak feature changes into "bug fix"...

    FSD v12.x (end to end AI)

    Not true, though I understand your point. You are not training/testing 4 (or N) distinct networks. You are training ONE network to respond correctly to numerous inputs, the "mode" being just one of very many more.. The "mode" is no more special than (say) the distance from a car in front of you...

    FSD v12.x (end to end AI)

    Yes, it's' more or less this. Many poisons can affect the brain, and in particular cause its tracking between (say) balance and the visual system to get out of sync. The best survival response is to get rid of the poison, hence vomiting. So it's not the ear per se, but the brains interpretation...

    FSD v12.x (end to end AI)

    No, the point is that the value is different depending on the buyers perspective and interest. I might value FSD very highly, and think I can get extra $$$ for it when I sell, but if a buyer never wants to go near FSD, he will not feel the FSD premium is worth it. For TESLA, as the "buyer" in a...

    Does he look inside the car (e.g. at a screen) or outside? When I was young I had bad motion sickness and it was always caused by looking down at (e.g.) a book etc.
  49. drtimhill

    FSD v12.x (end to end AI)

    But that IS the value you perceive. Sure, you try to negotiate, but if the seller wont budge and you do not see the value at that price, you dont buy.

    FSD v12.x (end to end AI)

    The "preferences"(like Chill mode etc) typically become inputs to the NN, with appropriate training data for each mode, though this can be expensive if there are many such settings (one reason Tesla keep them simple). Dont forget the NN doesnt just get camera data .. it also get map info...
