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

[Deleted member 17810]

You could argue that Tesla has done exactly that by switching to a 48V low voltage system. 48V components require lower current and lower current means less heat and less likelihood of ignition from a short. As long as you're carrying energy, you risk that energy igniting a fire. EVs are already several times less likely to catch fire than an ICE.

Agreed.

I don't suggest this, but if you want to experience it, while on a right turn using FSD accelerate past 85 rapidly and be ready to take over.

Why would any rational person do that?

Are you new to driving? Do you not understand that the only way to control a vehicle is through four small contact patches of the four tires? You need to respect the limits of your tires at all times and avoid abrupt maneuvers at high speeds that could threaten to overwhelm the available traction.

This should go without saying.

I'm hoping he was being sarcastic, and it just didn't come across. I'm actually surprised that FSD allows us to use the acceleration pedal to nudge it along and still continues. I've done this several times when taking a right turn because I think it's being too cautious or the person coming has waived me in.

Well, you have partially answered your own question.

FSD would be less safe in the hands of a reasonable driver if they took away the ability to speed up at will. And if the acceleration is drastic enough, and for enough duration, FSD will instantly hand full control back to the driver. Which is why Tesla says the driver must be attentive and ready to take control at all times.

This is common sense and it's not like the FSD team didn't carefully consider the pros and cons of different ways of doing it.

As long as the paradigm is "the human driver knows best", this has to be the case. But it will lead to the driver being able to make bad choices that the software would not make.

The doors and windows of CyberTrucks and Teslas in general roll down and open when sensors in the vehicle detect it is or is becoming submerged. This safety information generally known about Tesla safety standards.

I am not so sure that is true. A billionaire died in a submerged Tesla. The windows did not roll down. It wasn't a violent crash, she backed into a pond accidently and even called on her phone for help. She was on the phone for 8 minutes, in fear for her life. Breaking through windows in sometimes the only escape.

They do, but if you just drive into the water, there's a chance water gets into the electronics or doesn't trigger the collision warning. Collisions also always have a chance of the doors jamming as they resist letting the occupants be crushed.

It's more a thing of, 'don't drive drunk' than something wrong with the vehicle. There's no evidence in any of the articles that said she even attempted the emergency release. 10x the legal limit is just insanely drunk.

Also... have friends willing to wade into the damn water after you instead of waiting for police to respond, arrive, and do it for them.

I am responding to someone stating the vehicle rolls down the windows automatically when water is detected. There is a clear example of that not happening. Its nearly impossible to open a door until the vehicle is 100% flooded because of the pressure difference. An emergency release will not help with that.

Water can damage the electronics of the safety operation? That kind of defeats the purpose of detecting water doesn't it?

Regardless of the cause of accidents, whether it be DUI, speed, or recklessness, its in everyone's best interest for faults to be found and improved. I think the windows rolling down automatically (10 seconds after) all collisions and submersions (and actually working) would be an excellent safety feature.

Yes, because the vehicle was submerged.

But this is no different than any other vehicle. Eight minutes is enough time for it fill with water and attempt an escape.

As I said, the electronics have a chance of failing in water. The doors do unlock and attempt to release the windows in event of a collision. And a secondary problem of a water collision: It may not have triggered the collision sensors, No different than say, getting the car wedged somewhere.

As long as you're carrying energy, you risk that energy igniting a fire. EVs are already several times less likely to catch fire than an ICE.

The normal current in the circuit is less with 48V, but the fault power is either the same or higher.
The same if the feed is limited to 1/4 the original current (same max power). If not proportionally limited, the amount of power in fault condition could be up to 16x that of the 12V case due to 4x the current for the same resistance times 4x the voltage.
12V with 1 ohm short = 144W
48V with 1 ohm short = 2.3kW (assuming it can source 48A)

Speaking of narrow efficient tires. If anybody is actually gonna off-road their cyber truck, you better pray to God, those thin 35x10” tires stick to the bead if you do any sort of aggressive off-roading. Coming from over two decades of off-road experience those tires are basically UTV tires, yet on a 6,500lb truck. Keep them inflated as much as you can to prevent bead failure! or buy bead locking wheels . Alternatively , go wider tires to seat them on the wheels more securely. That’s my PSA , don’t say I didn’t warn you.

I was talking about this after I went off road and some people here didn't believe what I was saying it's all here https://www.cybertruckownersclub.com/forum/threads/tire-and-wheel-slip.28338/

Teslas are some the safest crash tested vehicles. One occupant was taken out alive. Reason would say the others would be too (restraints assumed).

As the leading mfg of EVs tesla needs to be finding a better solution to these fires.

Scientifically that's a hard ask, maybe dry cell is less combustable.

 

[rovert43]

And it was supposed to guess what you wanted and execute a maneuver it isn't qualified to do?

You overrode it. You did it, not FSD.


What fires? This didn't involve the battery. And BEVs burn less often than ICE vehicles.

You slam a bunch of metal into a wall and yes, sometimes that catches on fire. How do you think flint and steel works? Worse, everyone is carrying electronics which can spark, and you smash something contents that aren't supposed to be exposed are exposed. Don't try this with a lighter or vape in your lap!

"You overrode it. You did it, not FSD"
I don't want FSD to disable unless I turn it off. If I slam on the accelerator FSD stay on.
Comprende?

 

[rovert43]

You assumed control the instant you accelerated beyond the operating speed range of FSD. FSD didn't accelerate you to that speed, you chose to do so and by exceeding the cutoff, you disengaged FSD. The alternative would be for the vehicle to refuse to accelerate beyond 85 mph while FSD is engaged. It sounds like you learned a valuable lesson, if you're taking control of the vehicle to avoid something, you're taking control of the whole vehicle.

EDIT: I'll also point out, that if your avoidance maneuver had required hitting the brakes instead of the accelerator (which is far more often the correct choice), FSD would have immediately disengaged as well, leaving you similarly responsible for both steering and speed.

You weren't there, accelerating was the best move.

FSD should never disable unless the driver disables it.

Yeah. I'm new to driving. Don't be a moron.

I respect plenty of things, but not some fool that doesn't know how to have a conversation about improving features of a system that has obvious pit falls.
