That and the time and energy to compress the air. Elon never spoke about this beyond saying an electric compressor would draw from the man HV battery. It would take a LONG time to compress 75lb of air to 10kpsi

That's actually kind of funny.

Gasoline isn't as explosive as movies make it out to be; it's highly flammable, and will make a fireball, but won't have the same explosive energy as movies imply. Gasoline VAPOR is explosive, but usually the amount of vapor available isn't nearly as large. However if a 10kpsi cannister fails...

OK figuring out additional downforce required assuming that tire-to-road friction is the limiting factor is pretty straight forward. Honestly it took longer to write out than to just do the math. First of all we do know that tire-pavement friction is the limiting factor when accelerating...

Hey @Earl - do you mind editing your response so your comments are not hidden inside my code block? Cheers! I think if you just delete the code tags from your reply it should fix it.

OK I did the (or some) math (very quickly so feel free to check and correct me, but be kind I'm just doing this for fun) to figure out roughly how much thrust these cold-air rocket boosters would need to have; I then kept going to answer some other questions too ... I made a lot of...

Really, the most optimal direction to face the thrusters if using them for emergency control enhancement, is opposite the direction the car is sliding (again assuming sliding on ice or water and needing to regain control ASAP). A massive instantaneous impulse aimed opposite the vehicle's...

I mean, all this assumes the thrusters are a viable thing in the first place. I'll honestly be very surprised if Tesla and SpaceX engineers have come up with a viable, safe (key point there) way to store the claimed 10,000 psi (what Elon claimed on the Joe Rogan podcast). I also wonder what...

It's all plausible, but IMO the amount of thrust required to be meaningfully helpful in an emergency loss of traction situation (e.g. the ice/hydroplaning situation that @Earl described) is most likely way beyond what the thrusters will be able to provide. I haven't taken the time to do the...

I have no idea why you think rocket thrusters would be beneficial for ice or hydroplaning. What's your background in physics?

I have no clue. But there are quite a few in my area, where people love to throw away their money. Don't get me wrong, I'm a big proponent of solar and the original concept of the solar roof tiles Tesla/Elong proposed in Oct. 2016. But the current product is nothing like the one they unveiled...

October 28, 2016 at the solar roof event, he said the goal was to have a solar roof that "have an installed cost less than the cost a regular roof plus the cost of electricity; so why would you have anything else?" (EDIT: if you listen to that whole presentation, he repeatedly emphasizes the...

@Vagus - You've received great guidance from gearcruncher. I just thought I'd add what worked for me (and admittedly I may have gotten lucky). The line of inquiry I pursued was to state I wanted to schedule upgrades required for FSD-Beta. Once upgrades were scheduled, and the cost was quoted...

Elon's nothing if not overly optimistic when it comes to the results of a back-of-the-envelope "first principles" physics estimation of how well a thing will turn out. Let's not forget the solar roof claims! It was going to be CHEAPER than installing a new normal asphalt roof. That was the...

I have a sneaking suspicion that older/legacy cars may not get v12 since we don't have interior cameras for the nag feature. Someone who has a car without an interior camera and has v12, prove me wrong.... please! :)

This is totally unnecessary. Sure if there are problems, this is often the first thing to try. But after every update? I've never done that, and never had a problem after an update. As someone else said, the car reboots itself as needed with updates.

You might try to replicate my experience. Schedule the MCU and FSD computer upgrades, then simply ask them to waive the cost that you are asked to approve, and paste links to and images of their website from the internet archive, showing the statement that the car you bought was sold as having...

Fair enough. I was just responding to a notification, and forgot which forum this thread was in.

For those of you not following Reddit (I don't blame you) ... There's a mobile tech who posts there, and they just got FSD v12.3.2.1 (a new version) on demo cars running 2024.3.x last night. Hopefully we'll be seeing it pushed to owners cars soon. Would love to try FSD v12 for a month...

Did your upgrade include both the AP3 "full self driving computer" *and* the newer MCU? You won't likely get any FSD software pushed without the newer MCU installed as well. It's possible, but exceedingly rare. I've heard of only 2 people I think, across this board and Reddit who've reported...

I agree that mpg is more intuitive for Americans. But in my own geeky way I like W*h/mi because the units reduce to force. It's basically a representation of total drag force at whatever speed you're going. :D Watts = F*d/t Watt*hours = F*d Wh / miles ~ F*d / d = Force. You'd need some...

Recently had my MCU and AP computer upgraded, during which they wiped all my trip computer memories. So my lifetime Wh/mi is gone (was using "trip b" as the life time). Is there a different/better way to bring up lifetime consumption data?

My experience is that it does not offer me significantly more than what EAP/NoAP does for freeway driving / road trips. Yes, it offloads the stress of driving in the freeway use case, but not noticeably more than NoAP for me. While FSD might be slightly better in some aspects, both are...

Is this true for, say, hw3 cars not running FSD (e.g. base AP or EAP)? What about cars with hw2 or hw2.5?

Is there any evidence that in older cars that have radar, that it is used in FSD-beta? Or does FSD-beta (v.11 in my case) just ignore the radar (and USS) sensors?

Interesting. This is my take in going from EAP to FSD-beta v11 on HW3. Much more relaxed when approaching slower or stopped traffic. With EAP going 70mph on the fwy, it would just fly along until the last moment at which it COULD stop in time, and then slam on the brakes. Terrifying.

Here's the thing with FSD - are people going to engage it "so that they are safer" or are they going to engage it in order to offload some of the stress of driving. These are two very different cases, IMO. Before I had FSD, I had EAP with nav on AP ability. I used this all the time for...

Fixed that for you! :D LOL

Did you ever have Enhanced Autopilot? EAP included "Navigate on Auto Pilot" which was basically FSD on freeways only. It will navigate fwy interchanges and exits, even handle merging back into traffic after changing from one fwy to another. It will stop functioning at the end of a fwy exit...

Except that FSD v12 is only available to those with an older firmware. It's not available on 2024 firmware yet, AFAIK. So if you've got or want FSD v12, that's a good reason to not upgrade the firmware to 2024.

What hardware are you on? M3? MS? Year? HW2.5? HW3.0? Which MCU do you have? Cameras? All of these play a role in what firmware you will get. I have an Oct.2017 MS75. It was built with MCU1, HW2.5 (NVidia AP computer, updated camera suite). It wasn't even possible for me to subscribe to...

Long Range Plusest.

what that article talks about is the start of the >400-mile range, which was not the start of the LR+ model designation. LR+ were available with range somewhere in the 370mi ballpark (I forget how much exactly) before the 402mi range was released. They didn't change the model designation. So...

Well, this completely contradicts @tnixa 's claim of seeing Feb 2020 built LR+....

The internet archive is the place to go. https://web.archive.org/web/20170913053623/https://www.tesla.com/models As can be seen in the URL, that is a snapshot from 2017, September (09), 13th, at 05:36:23 time. You can move the slider to select a different time. I captured screen shots from...

When I wrote that, what I meant was when a service adviser or service manager initially says "no" to the request to waive the cost of a HW upgrade, they may not even be aware of the fact that Tesla promised our cars to have "all the hardware required for FSD" when we bought them in 2016, 2017...

Very probable. However I will highlight, that my contact, the manager of most of the service advisers at this service center, did agree up front and on a recorded call, to replace my autopilot computer (Nvidia based HW2.5) with the new HW3 computer, free of charge. So that part was not a...

I figure it's time for another update on my story here... (I know you're all dying to know, LOL) So the TLDR up front: I won't be pursuing a small claims court suit with Tesla for APHW and/or Infotainment issues. Why? Because they comped me the full upgrade, with FM tuner even. Long version...

from chatgpt/copilot:

Seriously though, what the hell is this? Makes me think this was an AI generated image, and the human forgot to check it. This fin-shaped thing doesn't appear in other images of the car.

I think I may have written that post. :) I wrote one similar anyway. The original AP option in my car was "APH3" which referred to HW2.5, not 3. But at the time of manufacture, they didn't call it 2.5; it was the Nvidia based AP computer, which was a step up from whatever AP2.0 had. So the...

with the tune in app? I don't recall ever having to sign in on my model S... will look for that. where do I look / how do I sign in / authenticate?

Dropped off car this morning. AND... they gave me a loaner for this work! I looked surprised and they said, yeah since this is something your car should have, it qualifies for a loaner. (even though my car is out of warranty). Interesting. FSD AP computer upgrade from hw2.5 --> hw3 computer...

I have a Model 3 on loan from the service center. My normal car is a 2017 Model S. When I type in a podcast title I want to find and listen to, into the M3's search, all it returns are songs and musical artists/albums from the streaming app - no podcasts and nothing from the "tune in" app...

Who are you talking about when you say "his past replies"?

Thought I'd post an update on my efforts with my sept-2017 built Model S75: (edit: FYI, I'm at 120kmi on the odo. Long past warranty for anything other than the motors and battery). Several weeks ago I scheduled an appointment for the infotainment upgrade and stated that my goal was to get the...

Ah ok my misunderstanding. Thanks.

@gearchruncher I noticed you edited the OP to say that you won "twice" ... what was the second case over, how was it different from the first claim/case?

I must say it's disheartening to hear that even people who are outright owners of FSD (purchased the feature with car new or upgraded at some point) not subscribers, are also facing resistance to upgrade MCU1 from Tesla. So, if I were to pony up the $6k to upgrade from EAP to FSD on my car...
