Tesla Hate Thread - oh and come seethe about EVs in general with me

[1Tonka_Truck]

I can barely even see any flooding. Looking at the tire on the golf cart, maybe an inch? Like holy fuck, it barely takes anything to set these fucking things off.

The water was probably much higher at one point. The water keeps the cells cool. When the water recedes, the cooling effect goes stops and the thermal runaway starts.

In other fun news a truck hauling one of the those 20' container grid batteries rolled outside the Port of LA. When the tow trucks came on scene, the doors blew out and it started burning.

Saltwater is highly conductive of electricity, even a little bit of this infiltrating the battery is going to cause shorts between battery cells, and subsequent fires. Storm surge water is salty.

See below, there is a dish filled with water, it won't readily conduct enough current to turn on the light bulb, but as soon as a little salt is added......

Others have already mentioned the water possibly being higher, but I have a different take. The worst possible scenario is salty water just reaching the battery pack but not actually submerging it. A fully submerged battery pack will be kept relatively cool (though this isn't a guarantee against fire), whereas one that the water is just kissing will short out and heat up like it's posting on twitter and someone called it fat.

I guess waterseals will be an important aspect of future technical inspections on EVs.

Current year liquid cooled car batteries are almost hermetically sealed as they're on the underside of the car and owners are expected to occasionally do stupid things like drive through 2' deep water. They need a small vent to equalise the pressure with the outside world and emergency vents (which are normally sealed) to let the gas out if the cells start to runaway so that the casing doesn't pop like a balloon.
You actually can briefly submerge the battery at a shallow depth with no ill effects, loads of clowns have driven Teslas through floodwaters and got away with it. The problems happen when the water is deep enough for the pressure to force water past the seals or through the vents or the car is submerged for long enough for water to seep through the vents.
The equalisation vent could be replaced with bellows like you have under the lid of a brake fluid reservoir, that would make them even more sealed.

Came across an interesting video about a Cybertruck in collision repair. The guy has a very open and honest discussion about his concerns, and what needs to be different with these trucks, from the insurance end to the repairing end. The whole video is worth a watch, but I timestamped it after he stops going over the damage from an exterior point of view. He does take the door off, and go over the interior damage, which was cool.

Summary:
- Truck hit a parking bollard and the mirror assembly and door smushed into the quater glass breaking it
- exterior damage looks minimal, but the interior parts of the door are weaker than the exterior, so that is where the damage was seen.
- door panels aren't really repairable, basically needs a whole new door
- 48V system can be dangerous to the other electronics in the vehicle, more likely to arc during disassembly, so everything needs to be denegergized de-energized
- luckily no damage to the A pillar as the softer internal door parts cushioned the impact
- appraising damage from pictures alone proably isn't going to be an effective way to estimate things
- using any kind of heat to aid in the repair process probably won't work because of the alloy of the steel

The towing company that was on scene when that grid battery cooked off posted their video.

The fire department wouldn't let them near it because it was already smoking, but they let them fly they drone.

In Vinnie's voice, "Boom, no more Chinese battery."

Rivian seem to have figured it out:

Cross-posting from the EV Ls thread, after Fisker went bankrupt, they abandoned their HQ and left it in a total mess:

Tesla cybertaxi revealed, and it is a two-seater (and a 3-door hatchback). It looks a little shorter than a Model Y, but most of the length is taken up by a long boot hatch.. The very obvious shape-obscuring disguise had you all speculating that it'd be some sort of weird pickup truck, so I still feel justified in saying you were all being autistic.

I watched the entire 10/10 robotaxi event. Took a really long time to start, like 45mins, but apparently that was due to a medical emergency in the crowd. I would have expected some kind of update on the livestream just to let people know what was happening, but there was nothing.

• There is a 'forward looking statements' disclaimer at the start (First time I have noticed that in a Tesla presentation)
• Musk gets into a Cybercab, and it drops him off on stage
• They designed 20 acres of Warner Bros studio into a small amusement park
• He rehashes a lot of the stuff that has already been said about "when we achieve unsupervised full self driving"
• Supposedly in late 2026 this will occur
• Doesn't talk much about the specs on the Cybercab which was disappointing, what's it made of, whats the range, etc.
• Hints at wireless charging
• Hints at automated cleaning stations for The Cybercab

• Reveals the Robovan
• Basically a small bus, no specs, nothing confirmed about it except this is "what it will look like"
• It looks like an art deco train to me which pleases my autism

• Lots of hinting in the vehicle portion but not much meat.
• They talk about optimus, and restate how it's going to be your personal C-3PO.
• They release a couple dozen of these to wander in the crowd
• Presentation portion ends
• The camera's then pan around the crowd for another hour, and you see optimus doing things like
  • Go-go dancing
  • Handing out gift bags at a station
  • pouring drinks at a station
    • They kept cutting away before you could see the robot pour the drink but close to the end they finally let you see a full drink pour (sus)

Someone is going to slap prosthetic breasts on these things for sure.

Overall the presentation was designed for the people in attendance, and not really for the viewers of the livestream. There was a large focus on getting people to drive around Warner bros Studios in the Cybercab rides, and interact with the Optimus Robots. They also had carnival games etc. It was a Tesla-styled mini theme park. Optimus really saved the presentation, because it was the only thing really interesting to look at, after the skimpy details on the Cybercab, and Robovan.

They can talk now? Real or remotely? How much of this is autonomous?

There was a noticeable bouncer presence around all of the Optimus Robots, they constantly told people to stand back, etc, they were VERY protective of the robot, or perhaps were very afraid of it hurting a patron, it wasn't unsupervised free roaming.

I'm pretty sure those robots were being controlled by someone with a VR headset and shit. I saw this video of someone standing and talking to one and it was way too responsive, quickly, and a completely natural smooth speech. No way it was AI talking on the fly. https://x.com/i/status/1844619047507259900

If it was all the robot, then they've made HUGE leap forward as I've not seen anything else come even close.

Looks like couples with kids, people with more than 1 friend and single parents with more than 1 kid will have to wait for a CyberArtDecoTrain to show up.

In 2021 is was just an underpaid dancer/actor in a bodysuit so things have progressed somewhat.

The bar tender demo is bullshit, the glasses are all indexed so it's very easy to automate without complex vision systems. What vision that might be used couldn't tell if the glass was properly full. I also notice that there isn't much foam in the beer, possible they are running the CO2 low to keep the feed more consistent so a simple timer can be used. The idea is it's supposed to drop into human labor but this is a job we've vending machines for that do a better job.

As to vision and robo taxis in general, when Tesla can run those stupid taxis in tunnels in Las Vegas I'll believe they have made some viable progress on automation.

The demo still showed some impressive hardware. What's lacking is the software, but unlike hardware, software is easy to modify. This generation is decidedly more impressive than the ASIMO of the past. If it can be remotely controlled by a human operator, it can be remotely controlled by a neural net in a datacentre somewhere.

That's a deceptive line of thought used to convince the world we would have self driving cars by now, and that it's perfectly fine to finish making games after they launched.

For the most part we do have self-driving cars. The risks of operating an automobile in traffic are significantly greater than those of a robot that can serve you breakfast in bed, if it sometimes trips over a rug and drops its tray nobody is going to die.
I think we all would rather have a fully developed product that runs all its software locally, and also that software is already in good condition and doesn’t need continuous patching, but that’s not what the real world looks like anymore.

Did you completely forget that Tesla sold an entire line of cars with the promise that they will get a software update to full unattended self driving, only for that to prove impossible?
