    Wiki MASTER THREAD: Actual FSD Beta downloads and experiences

    Can you elaborate? The projected path was straight ahead the entire time. Stepping frame-by-frame, the car slowed from 40mph to 25mph by the time it entered the intersection (while the light was still yellow, barely), then braked further to 15mph within the intersection before I overrode it. On...

    FSD Beta Videos (and questions for FSD Beta drivers)

    Definitely worth a rewatch, now that I've had firsthand experience with the beta! Is it your understanding that the NN is completely in charge of the red light (mis)behavior seen in the video? Also wondering if perhaps the lane guides within the intersection confused the network and made it...

    FSD Beta Videos (and questions for FSD Beta drivers)

    Here's a short clip of FSD Beta 10.5 in my Model 3 from this evening. This is fairly typical of my experience with both 10.4 and 10.5. High level of alertness required! Particularly concerning is the bike lane incursion at 0:42 and red-light braking at 1:05, but the car makes several mistakes...

    Tesla FSD Beta Release 10.5 2021.36.8.8 - 10.5.1?

    Trying out 10.5 on some of my usual routes. There's a spot where it has to make a left turn (two left-turn lanes) followed by an immediate right (200 feet later); the car still always incorrectly chooses the leftmost of the two left-turn lanes, and is unable to merge over to the right lane for...

    Wiki MASTER THREAD: Actual FSD Beta downloads and experiences

    First drive impressions today with 10.5. Overall not substantially different from 10.4, although I was using it on mostly different streets. Some highlights: - Got completely lost trying to get out of an easy parking lot; started driving across marked lines and around in circles. Finally gave...

    I've heard comparisons between horses and autonomous vehicles before, but this takes the cak.

    Just installed 10.4 (2021.36.8.5). Any tips/tricks/advice?

    In theory, theory and practice are the same. In practice, they're not. 😜 Just stay alert and you'll be fine. There's no substitute for simply using it for a few days to get used to its "personality". Lots of phantom braking, lots of basic mistakes (choosing the wrong lane, stopping in the...

    Wiki FSD Beta 10.4

    I'll try to get used to this. The throttle doesn't disable FSD though; I think that was my instinctive hesitation, that I'd rather disable FSD than fight with it. But I'll try the throttle the next time it happens. Right, but my thought was less about stop signs (or any situation where the car...

    Wiki FSD Beta 10.4

    My Model 3 very nearly caused an accident on FSD Beta 10.4 today. Driving on a 35mph street with moderate traffic, it spontaneously phantom-braked HARD (like ABS-hard), and the car behind me had to swerve out of the way, very nearly colliding with me. This is a particular problem because phantom...

    FSD Edge cases

    Not to put too fine a point on it, but recent shortages of veterinary ivermectin would seem to refute this. Regarding L4: I've driven (or been driven) many thousands of miles on highway NOA, and it is nowhere close to L4. I'd guess that it currently requires an elective disengagement about...

    Wiki FSD Beta 10.4

    Same. A big part of the problem is the halting and jerkiness; it makes it much less obvious (to me, in the moment) what FSD's intentions are, so I'm more likely to disengage. I've had it stop completely in the middle of an intersection several times, even with a green arrow and no cars ahead of...

    Wiki FSD Beta 10.4

    The other thing Autopilot has never figured out is how to handle a single lane splitting and becoming two. It always sees the lane widening and goes straight down the middle, then panics and swerves when it sees the "gore point" approaching. A much more reasonable approach would be to hug the...

    Wiki FSD Beta 10.4

    First #FSDBeta impressions (10.4): I was thrilled to get to finally try it out!! Impressive in some ways, but very far from prime-time. 15-mile drive through Pacific Palisades, ten necessary interventions/disengagements. I’ll list what I can remember: 1) Phantom forward collision warning on San...

    OFFICIAL BUTTON WATCH

    I wonder if at some point the safety score can be separately calculated and shown per driver profile, even if the combined score is still what counts for FSD eligibility. It would also be nice if they excluded Track Mode (geofenced to tracks). And I would hope that the AI would eventually be...

    OFFICIAL BUTTON WATCH

    The score is calculated based on the "moderate" setting, regardless of how you have the car preference set. So it may even be better to set the preference to "Early", to give yourself a chance of reacting to the early audible warning before it reaches the moderate trigger level.

    Falcon Super Heavy/Starship - General Development Discussion

    Starship doesn't have an orbital booster to do this with, so you'd need two Starships. (It could technically be one crew Starship and one cargo Starship, but artificial gravity is pointless for cargo; you'd maximize payload capacity by pairing up crew Starships with tethers, and leaving the...

    Falcon Super Heavy/Starship - General Development Discussion

    Agreed that "what problem are we trying to solve" is the right question. My assumption was that there are two main goals: first (and most importantly) to keep the crew in optimal physical and mental health during the long trip, and second, to gradually acclimate the crew to the gravity at the...

    Falcon Super Heavy/Starship - General Development Discussion

    Nice thoughts! Starship is 50m long, so it may be too short for meaningful artificial gravity in tail-to-tail configuration. (Starship + Super Heavy is 120m.) At 2rpm spin, gravity in the crew compartment (~10m from the nose) would be about 0.15g. Having the spacecraft rigidly connected would...

    Falcon Super Heavy/Starship - General Development Discussion

    I think the idea would be to wait until the starships are fully loaded, before the spinning starts. Docking to a spinning configuration like this would be incredibly difficult, even at a very low spin rate.

    Falcon Super Heavy/Starship - General Development Discussion

    #3 should be solvable by building some flex into the tether, so the tension doesn't have a step-function; imagine using "bungee cords" at either end to give the system some play. Or with an adaptive friction mechanism to simulate the same thing. Or, instead of having the Starships get up close...

    Falcon Super Heavy/Starship - General Development Discussion

    The launch loads are compressive, and distributed through the thrust puck. Artificial gravity loads would be tensive, and would need some sort of distribution from the tether attachment points. In hindsight, Starship is already clearly liftable by a crane, so presumably whichever attachment...

    Falcon Super Heavy/Starship - General Development Discussion

    I would think that onboard gyroscopes/flywheels ought to be able to compensate pretty well for transient stability issues, without requiring propellant. (Some propellant would be required to spin both Starships up/down, but it might be enough to use ullage gas that would be bled off anyway.) It...

    Falcon Super Heavy/Starship - General Development Discussion

    Thanks for the link! It seems that ~3rpm is the upper limit for comfort without requiring specific adaptation, so a ~200m tether should be sufficient for 1G acceleration. (For more comfortable 1G @2rpm, a ~450m tether would be required.) Unanswered questions for the feasibility of this idea: 1...

    Falcon Super Heavy/Starship - General Development Discussion

    It occurred to me that if Starship uses a similar catching mechanism as Super Heavy, the load-bearing catching arms would make perfect attachment points for artificial-gravity tethers. Envision two Starships en route to Mars, noses facing each other, 500m apart, catching arms connected via...

    Tesla app version 4.0.0 has app re design for both car and energy

    I was looking for this too. My inverter is having an unusual problem where it clips to 1.8kW when grid-connected, but stops clipping when e.g. the grid is down in a power outage. I was looking forward to testing this with "Go Off-Grid", to see if I can get full performance out of the inverter...

    Does anyone know how to access the "Go Off-Grid" feature advertised for this release? My inverter is having some issues that cause it to perform better when decoupled from the grid (it clips to 1.8kW when grid-connected, but doesn't clip during e.g. a grid power outage), so I'd like to try...

    Tesla AI Day - 2021

    Agreed the Dojo presentation was amazing. I think Tesla Bot is very much in keeping with Tesla's aesthetic, in that it goes for the sleekest form factor from day one (no protruding backpacks/wires/etc, just as the car has no LIDAR/antennas), and the tech follows within that constraint. The haiku...

    Underground Mars Habitat?

    An interesting idea I remember hearing about is a "waterlock": a U-shaped tunnel that goes _down_ from the pressurized underground habitat, then sideways, then up to the surface, all filled with water, which astronauts would swim through (while spacesuited) to get to and from the surface...

    eMMC shadyness + Tesla

    I recently had my eMMC replaced, and the process wiped out my trip meters and HomeLink settings, among other things. I would think that if your eMMC had been replaced before, you’d know. And yes, they should have replaced it whether the original chip was still working or not.

    Poll: Which will come first: Person landing on Mars or U.S. wide level 4 FSD?

    “Corrected”? Or to put it another way (and this could equally well be called Elon’s Law, especially as it applies to FSD reaching production): “Hofstadter’s Law: It will always take longer than you think, even when you take into account Hofstadter’s Law.” To be clear, I am a huge fan of...

    Poll: Which will come first: Person landing on Mars or U.S. wide level 4 FSD?

    I interpret the FSD poll choice as “First car approved+available for non-geofenced L4 on all US highways and streets”; not necessarily that such cars would be widely available at that time. (Though with Elon’s model they will be, even if that means HW4 or HW5; the hardware will always predate...

    First details of starship's first orbital test flight!

    I’d call it close enough to orbit for all practical purposes.

    First details of starship's first orbital test flight!

    The question is whether the flight will be on a ballistic trajectory (perigee in the atmosphere), or whether it will be in a true orbit and have to do a deorbit burn. Could a purely ballistic approach be precise enough to control the exact reentry+splashdown point, at such a shallow angle?

    New Charity Bet: Date of first time Starship reaches orbit.

    I wonder if it will be placed on a ballistic trajectory to reenter, or if it will have to perform a deorbit burn. In the latter case, that obviously counts (to me) as fully orbital. In the former, if it achieves ~99% of orbital velocity, and letting the engines run for three more seconds would...

    New Charity Bet: Date of first time Starship reaches orbit.

    The short-term depot idea is exactly how I pictured it: launch 6-8 tankers over the course of a few days, keep one in orbit and fill it to 90% from the others, then launch Starship to rendezvous and top off. Especially for crewed Starships this makes much more sense than sitting in orbit for...

    New Charity Bet: Date of first time Starship reaches orbit.

    My understanding was that fully refueling a Starship on-orbit (for e.g. Mars departure) always requires 5-6 "tanker" launches, since the tanker will use 85% of its fuel on the way up and only have 15% left to donate in orbit. And for economic purposes, all of these tankers will have to be...

    New Charity Bet: Date of first time Starship reaches orbit.

    I don't expect there to be a difference in practice; i.e. I fully expect SpaceX will reach both milestone definitions with the same flight. Of course yours is the one that counts for the bet. Tanker and Starship configurations are both Earth-landing-capable (are they not?), and I'm sure the...

    New Charity Bet: Date of first time Starship reaches orbit.

    I'm in for first Starship to orbit. (To me that means first Starship to have a nonzero chance per Elon of successfully deorbiting and landing. Soft water landing counts.) 10/31/2021.

    Autonomous Car Progress

    It's less about total resolution and more about angular resolution. I predict future HW revs might have gimbaled telephoto cameras (at least two, for redundancy) to be able to rapidly "investigate" areas of interest picked up by the wide-angle cameras, such as faraway speed limit signs or small...

    "Elon’s tweet does not match engineering reality per CJ." - CJ Moore, Tesla's Director of Autopilot Software

    Acknowledged, I wasn't aware there were such configurations out there (with HW2.5 + NoA). Thanks. Is there footage of what happens when a FSD Beta car is driven onto a highway/freeway? Does the FSD Beta visualization stop working and revert to non-beta mode? Or does it keep the beta...

    "Elon’s tweet does not match engineering reality per CJ." - CJ Moore, Tesla's Director of Autopilot Software

    Acknowledged. I think it was coincidence that my 2017 Model 3 got its Hardware 3.0 upgrade at exactly the same time NoA was introduced, so I incorrectly assumed they were connected. Also since current Tesla packages bundle them together (the $10k FSD package states that it adds both Hardware 3.0...

    "Elon’s tweet does not match engineering reality per CJ." - CJ Moore, Tesla's Director of Autopilot Software

    I used "FSD 8" loosely to describe the version of FSD currently accessible to all drivers who have purchased FSD, though maybe it technically refers to the current pre-9 limited beta, so the general fleet is still on "FSD 7"? (My car is currently on 2021.4.15.6.) And since the car has highway...

    "Elon’s tweet does not match engineering reality per CJ." - CJ Moore, Tesla's Director of Autopilot Software

    Every ~3 miles in city driving; much better on highways. FSD 8 causes me to intervene "for safety" every couple hundred miles on the highway in my experience, with perhaps 1% of those interventions "actually needed" (i.e. would avoid a crash), so I'd estimate FSD 8's L4...

    "Elon’s tweet does not match engineering reality per CJ." - CJ Moore, Tesla's Director of Autopilot Software

    I interpreted his quote differently. He says three things: 1. FSD 9.0 is still being improved. 2. The ultimate goal is to get FSD to 99.999999% on city streets at L4/L5. 3. Autopilot is already above 99.999999% on highways at L2. This does not mean that existing AP is "better" than FSD in any...

    "Elon’s tweet does not match engineering reality per CJ." - CJ Moore, Tesla's Director of Autopilot Software

    Not all interactions are alike. As the system improves, the vast majority of interactions/disengagements will become "optional"; the human driver may take over out of impatience or feeling like they can do a slightly better job, or if they see a situation they're not 100% sure the car can...

    Autopilot - Carpool Lane Fail

    Agreed on all counts. Another feature I'd love to see based on the seat sensors (but which also is no doubt very low priority) would be for the car to track "Watt-hours per passenger-mile" as a statistic. For those trying to hypermile, it would really emphasize just how important carpooling is!
