    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.

    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.

    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.

    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).

    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.

    Model 3 Highland LR Range after charging

    Charge it to 100%, leave it for a few hours to let the BMS do its stuff, then check.

    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.
  14. 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%...

    But others (including myself) have .. so its an issue.
  16. 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...

    FSD v12.x (end to end AI)

    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"...

    It's done that for me too. So +1 for rabbit-kind :)

    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...
  33. drtimhill

    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...

    Yeah that all sounds familiar .. as you note it's something that they usually grow out of (just about the time they grow into all the other things you were fearing!!).

    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.
  37. 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...

    FSD v12.x (end to end AI)

    A very good question. In all the time that people were anxious about PB (and reporting many events), I dont recall anyone actually saying they had been rear ended as a result.
  40. drtimhill

    FSD v12.x (end to end AI)

    Of course, and I'm not saying you should. The point was the assumption people made that the car would ALWAYS brake that way no matter what was behind them.

    FSD v12.x (end to end AI)

    But that's because the purchaser of said computer would also have to buy Windows if it wasn't included. But Tesla dont have to buy anything from anyone to add FSD to a car. And so it would be with Microsoft, why would they pay extra money to buy a computer with Windows on it? When you are...
  42. drtimhill

    FSD v12.x (end to end AI)

    While Tesla have not said so explicitly, it's pretty clear that the car takes into account the probability of being rear-ended when it handles emergency braking (remember is always knows the distance to the car behind, and the software can handle the decision making process in a minute fraction...

    FSD v12.x (end to end AI)

    Well a "fair" test would use a real human (even a child!) .. and there you are drifting into an ethical nightmare. But even is it wasn't seen as a human, it stopped for the obstacle, which seems to be a good outcome.
  44. drtimhill

    FSD v12.x (end to end AI)

    I would imagine that is the intent .. though a lot of ppl are NOT going to be pleased since what is now "FSD (Supervised)" was once positioned as much more L5.

    FSD v12.x (end to end AI)

    Having scrubbed back and forth I think I agree .. the audio alarm kicks off at 0:11, the dash warning appears at 0:13. In my experience these are usually simultaneous. You can hear the brake pedals applied too, but it's tricky to see when the car starts slowing. I'd say the car doesnt see the...

    I was trying to allow for that and also observe the dash warnings as well.
  47. drtimhill

    FSD v12.x (end to end AI)

    Not sure what to make of this .. the alarm seems to go off before the dummy appears .. but perhaps that's the camera angle. If it is faked I'm not sure how they did it cause its hard to fake the various warnings and dash icons etc.

    FSD v12.x (end to end AI)

    Of course it has no trade-in value. Why would you expect otherwise? Since it's software, Tesla has an infinite inventory of FSD upgrades at zero cost to them, so how could it have any trade-in value? You might as well try to sell your copy of Windows back to Microsoft.

    First two Tesla road trips: Jones, AL, and Washington, DC, from Boca Raton, FL

    A couple of general comments based on my experiences taking long trips... First, get a keycard "ring" as a great backup for car access. Since it's attached to your finger, which is (hopefully) not detachable, you will always have it with you. I swim and surf a lot, and use it all the time so I...

    Wiki MASTER THREAD: Actual FSD Beta downloads and experiences

    Well exactly .. ideally the car should do that and maybe even dial 911. But it clearly should not just give up driving and let the car swerve and crash.
