Cybertruck hit head on in wrong-way crash on I-10 Houston. Both drivers killed

[pricedm]

Thanks. None of those have another vehicle driving straight at it at the same speed or higher than the Cybertruck. This is equivalent to a tree jumping out in the middle of the road if you were going 150mph…..

Go to the 4th embedded video (" Training data curated from the entire fleet") and there's a potential head-on collision at 0:10 that shows FSD reacting and avoiding a collision.

At highway speeds a wrong-way driver is such a difficult and fast situation.

For the life of me, I cannot understand how anyone thinks everything is normal (even under the influence of drugs) driving the opposite way down a freeway. Do they think that they are right and everyone coming the other way is somehow wrong?

I’m wondering if the first impact (head-on) was survivable, without the second (tractor trailer) impact.

 

[REM]

OK, @Crissa, I'll bite.

Why the sad reaction? (or whatever reaction that is called?)

Because you percieve I have a lack of sympathy for someone I don't know who died (out of estimated ~8-billion people currently alive...)?

Or maybe my copy-n-pasted very same words used by "that guy" were offensive?

Or maybe just because two forum members don't have the exact same opinion?

Or maybe door #4: none of the above... care to share what it is?

She's still skulking around this forum?

You can die falling from a chair; it doesn't even need to be a big chair.

Panic.

The driver might think "I'll just get off at the next exit" instead of pulling over. They might even speed up "to get there faster". People made terrible decisions when panicked.

Also, it was late at night, so the Cybertruck might have been the first vehicle they came across.

What would you do? I'm inclined to brake hard, even to a complete stop, because it's hard to predict how the other driver will react.

No
Forces
2 cars each going 60mph hit head on.
Same as:
A car going 120mph hitting a steel reinforced brick wall.
You do not survive that impact.

Okay, there's a little physics to clear up:

When you come to a stop in such a collision, you're only feeling your own deceleration. You don't feel the deceleration of both vehicles. So it's like hitting a brick wall at 60.

However, it is partially right, in that the metal structure experiences it like it hit a brick wall at 120. Except it's not brick, it's another collapsable vehicle.

The first impact was bad enough to kill; the secondary impacts only compound the injuries. Safety equipment can only do so much - it only reduces your chance of dying. You can die falling from a chair; it doesn't even need to be a big chair.

(emphasis added)

Potentially. But odds aren't good.

Needs hug emoji.

Two identical mirror image vehicles colliding when each are going 60 is the same as each car hitting an immovable/incompressible object at 60. Like hitting a force mirror.

M=single car mass
V=single car velocity
Ke= 1/2*m*v² + 1/2*m*v² = m*v²

A single car going twice the speed (120) has the energy:
Ke= 1/2*m*(2v)² = 2*m*v²

Aww shit! @mogo’s doing physics up in here! Everybody step back, give the man room!

Sweet heaven, might as well be hieroglyphics to the untrained eye..

Just curious what safety equipment/gadget you guys carry in your CT. I agree some safety equipment is better than nothing.

A Satellite phone with pre-programmed emergency numbers for N. American hospitals and emergency medical transport companies, personal locator beacon, emergency escape hatchet, a stretcher, 4 tourniquets and homeostatic dressings, assorted bandages and tape, portable oxygen system and tank of oxygen, emergency bag-valve mask, defibrillator, Electrocardiogram machine, infusion pump and assorted infusions including the eight most common blood types in a 120V refrigerator (3 liters of each), sutures and various needles, gloves, alcohol wipes and towelettes, a gallon of water, smelling salts, morphine, a selection of anti-coagulants and blood thinners, LifeVac and a space blanket.

I know this might sound excessive to some but with how dangerous the Cybertruck has been reported to be, one can't be too careful!

You might be surprised what kind of head-on collisions are survivable in a modern car, and especially in a Tesla that has the capability to begin airbag deployment before the actual moment of impact in high-speed frontal collisions (they leverage the data from the cameras).

As @mongo pointed out, the impact is not 60 mph plus 60 mph, it's just 60 mph (because both cars have crumple zones it's similar to hitting a wall going the original speed).

Obviously, there are a wide range of outcomes that will vary with the exact particulars so I don't want to be testing these high-speed head-on impact scenarios, just know that it is not certain death.

I'm not an expert, but that's assuming the exact same vehicles hitting each other at the exact same angles, etc. (In a vacuum haha). Dead center on the car would respond different than near the corner. Point being, it's not exact, but their point is it's not like 120, it's closer to 60. And you would think that the heavier vehicle (Cybertruck) more likely goes through the lighter vehicle more. Ex: If a car hit's a bike, the bike takes it much harder. Just spit balling here...

I'm not fond of posting AI results, but this is an accurate summary of the articles referenced:



Survival in a head-on collision depends heavily on speed; at lower speeds, survival rates are high, but at higher speeds, the risk of fatal or disabling injury increases dramatically. For example, at 50 mph, the survival rate drops to about 31%, and at 70 mph or higher, the chances of survival are extremely low.

Other factors include the angle of impact, whether drivers brake, and vehicle safety features.

Speed is the most critical factor

• Higher speeds drastically decrease survival chances.
  For every 10 mph increase in speed, the risk of dying in a crash roughly doubles.
• The 40 mph mark is a key threshold.
  The Insurance Institute for Highway Safety considers a 40 mph frontal crash a severe collision. Some crash experts suggest that 43 mph is the line for survival in some head-on impacts, with speeds above this significantly increasing risk.
• High-speed collisions are often unsurvivable.
  At speeds of 70 mph or higher, fatalities are almost guaranteed, especially in a direct head-on impact.

That's all true statistically. But it doesn't detract from anything I said about 60 mph impacts (which is still true and valid). A 70 mph impact is much more violent than a 60 mph impact.

That said, I do suspect the average speed of the two vehicles under discussion was MUCH higher than 60 mph!
