Tragic Cybertruck Accident in SF Bay Area Kills 3, Injures 1

[2000prerunner]

One bad thing about teslas complete lack of participation and concern for motorsports, is they don’t learn things about driving fast. For example, BMW Benz , Audi so on , probably discovered ,after half a century of racing ,that using massive rotors, DOT4 fluid ,warm sticky brake pads, was a good idea to prevent their cars form hitting the barrier. Also , things like very wide “not efficient” sticky tires , suspension pivots that are not mushy , and shocks that work well past 90mph over bumps in the road play a key roll in not unsettling the car and losing control.
Tesla does not care about these things so much. Which is ok for a 200hp Toyota sedan , but not ok for a vehicle capable of 350-1100HP.
for those of you people who have previously owned proper sports sedans or sports cars you probably know what I’m talking about. The first time I test drove a model 3 dual motor , I immediately knew I had to buy the performance because of the shit breaks and suspension . I legitimately thought it was a safety issue. Even when I got my model 3 performance, I ended up tossing, shocks ,suspension links and brakes in the trash in favor of aftermarket ones + Wider tires in the rear (285mm like bmw does in order to not kill their customers in a “sports” sedan ). My model Y duel motor is always in chill mode with speed limit set b/c I’m aware it’s basically a minivan as far as brakes /handling goes. If you own a plaid and you’re not suicidal , i’m sure you have already upgraded to big brakes in order to prevent an early demise.
I’m not saying any of those things could have saved those kids from crashing their cyber truck. But Tesla has a major problem. They give common peasants half a 1000 hp with Toyota Corolla like brakes and suspension on a lot of their cars. Even their performance/ plaid trims require lots of aftermarket mods if you value your safety. Most responsible people won’t break the law and speed like crazy, but giving ppl the option to do so without an additional layer of protection from race like breaks and suspension is irresponsible. I called it years ago after owning a few Teslas and coming from BMW / Benz. Expect to see more naïve people dying in their “quick” Teslas because they’re narrow all season tires with shit brake pads , caused them to slide into the concrete barrier.

...And an ICE powered vehicle has no inverse torque to trust at a moment's notice, nor are their brakes liquid cooled like the motor on an EV.

So again, apples to oranges.

My kids get to drive all our cars. I monitor the speed via Life 360. They lose 0.05% of each person's inheritance for every personal set thresholds on an annual basis. Also driving in the dead times. 1-4 am are not allowed. I guess it is all different for all the kids out there.

What would be the ignition and fuel source in a solo EV car crash, though?

In an ICE car, there's plenty of volatile gas vapor available. In an EV, if not thermal runaway of the battery, what would be the equivalent fire source?

Gee, I dunno... arcing of high voltage from a battery that can supply nearly a megawatt?

That power doesn't exist in the cabin. But there are hot parts being strewn in such an accident, surfaces that shouldn't touch touching, brake fluid can flash over, any of the low voltage systems can spark and plastics burn.

I think I understood that the fire in this crashed CT case was not due to a runaway battery. but rather just the materials in the cab which means that they must be fairly flammable for it to burn that fast. Not having a real combustible fuel source like with a runaway battery or spilled gasoline or vapor. maybe they were making moon shine? But I think this should be a real concern. why go through all the trouble of making the battery safer and less likely to have a complete meltdown or runaway event and if it does it's limited to only affecting 25% of the battery in most cases since it is divided into 4 isolated compartments that include buffer zones on sides and the whole bottom so there is two metal skins with air space between the two for better protection with penetrations to the battery. And not only that the bulk of the fire and energy from a runaway event is redirected in a predetermined direction and escape path through the buffer zone and out to prevent the flames from entering the cab area they go down and out the bottom of the vehicle through exhaust ports that point down. but if the martials in the cab are flammable enough to kill everyone inside before emergency crews can even arrive at the scene. I mean this seems a bit counterproductive or careless engineering. and if so, is this case why not have some sort of automatic fire suppression system at very least a fire extinguisher somewhere inside the cab. shit even good old sprinklers that pop when temp gos up.

Sprinklers connected to what large source of pressurized water?

Again... the battery doesn't itself need to be compromised to supply energy to a fire: any damage to HV wiring that is connected to the battery and which cannot be fused to low current (wiring to the motor(s) or DC charging infrastructure) can also provide enormous amounts of heat energy that will ignite and support combustion of anything even remotely flammable.

While this is true, none of this wiring is in the cabin.

And if the impact pushed it into the cabin, well, that's one heck of an impact!

There's no evidence they were killed by the fire, though.

And plastics, brake fluid, clothing are all flammable to some degree. As well as the airbags, seatbelt tensioners. Not to mention alcohol, lighters, butane, vapes, and personal electronics. Heck, hand sanitizer, some cosmetics, deodorants, cleaners - these are also specifically accelerants.

Just slamming metal into another, hard object will create sparks. Slamming an object filled with other breakable objects which can burn can cause a fire of the objects stored inside.

There's no mystery here, nor is there any evidence anyone engineered anything wrong.

Sure, you could imagine a case where the accident was severe enough that the impact broke open seat belt tensioners and caused a fire... but this is the only case we know of where the pack was not destroyed and there was a fire. Hardly a pattern.

Maybe you meant drive their Cybertruck (which I agree is next level in terms of risk with a young driver and I have not allowed my kids to drive mine). As for Teslas in general, that's all I let my kids drive. They can be speed/power limited, they are easily monitored through the app for random checks of speed etc, they record video that can be reviewed after incidents and are built to withstand severe crashes (no vehicle is perfect but Tesla is very focused on crash-worthiness). The extra mass of the vehicles is generally a plus too. As a practicing emergency physician and EMS medical director, I've seen a lot of fatal wrecks over the years and sometimes physics and physiology just come together in an unpredictable way leading to death no matter what the vehicle.

Not sure if that is a slight or not. We used to put crosses at all fatalities that are known in Montana. American Legion does it last time I remember. Stark reminders of death in front of your face.

Well like I said. All kids are different. They look at cars as transportation like father. Utility vs. flashy.
The bank account should matter more than the flash whatever it is. Mine are young adults now. While I don't track them any longer, I still ingrained safety first principles.

Well raise a little more than an idiot, and I would think a Tesla is a great car.

We agree on the at night aspect. Many states have rules for kids driving past certain hours.

Putting a responsible driver at any age in a Tesla is a good idea. If one's child or anyone for that matter isn't responsible they shouldn't be driving. It isn't a crap shoot when you put a kid in a car. My kids didn't get licenses till 17.

Putting a kid in a jolipe. Well one must not care much about the future generation of fill in last name.____________. I always love that. I am going to put my kid in a piece of crap car or truck so they can go bump around it will be good. They can't drive it fast. News to all you moron parents. Crap cars go fast. They crash like crap as well. Hope the insurance is up, and you have a burial policy for young johnny and the family they kill at a traffic light with a crappy car.

Not a slight at all! I think it's a great idea, and both a great way to teach about consequences to actions, and mindfulness in the moment.

Or you can use FSD and it’ll generally keep
You out of trouble. Don’t think you could drag race using FSD.

I would disagree with this.

Accelerate while FSD is engaged, ignore the warnings about taking over that will inevitably happen, die, all the while thinking the truck will save you from being too stupid.
