Tesla driver loses control as car speeds down street
That’s Tesla’s position…but no.
The man had been complaining about the brakes not working properly for months according to his family (yet kept driving, making him culpable imo).
It’s easily possible his brake sensor failed on the pedal, then there would be no light. Since I assume, to be capable of autopilot, Tesla brakes are by wire/electrical, not hydraulic, a simple sensor failure means no brakes at all and no brake lights. (And no record that he hit the brakes)
Again, never once heard of a panic pedal misidentification lasting 1/2 that long. Possible, but unlikely. 99/100 of pedal misidentification are well under 1 second mistakes during parking. There have been many reports of throttle sticking/ accelerating without throttle input in teslas.
Since Tesla denies fault EVERY TIME NO MATTER WHAT, and hides the vast majority of driver assisted crashes, I’ll wait for the third party investigation, but on the surface, to me, it looks like a software (or hardware) failure….and that’s what the driver says too.
Not that I want to be siding with the corporation, but I'm inclined to believe that at least the brake lights would've remained connected to pressing the brake pedal, no?
And... not seeing any brake lights in that video, it looks like driver error and then panic.
Making Spherical Tanks Through Explosive Hydroforming
From YouTube videos description..
Explosive hydroforming, also known as HERF (High Energy Rate Forming) or exploform, is a striking alternative to the more traditional process of metal hydroforming. Unlike this older method, which shapes metal using pressurized hydraulic fluid pumped into a forming chamber, HERF techniques utilize an explosive charge to create the necessary pressure. Although the charge is relatively small, it is capable of generating enough force to mold the associated metal into the die.
The explosive charge is typically positioned at a specific distance from the workpiece, and both are immersed in fluid, usually hydraulic fluid or simple water. Certain facilities may also use oil, gelatin, liquid salts, or regular air as the transmission medium. However, water is the most commonly used medium as it is the least expensive, excellent for creating uniform peak pressure, and readily available. Once the charge and workpiece are properly positioned, the charge is detonated, pressing the workpiece into a die. The part is then removed and the process is repeated if necessary.
Explosive Hydroforming Methods
Explosive hydroforming techniques fall into two basic categories. Although both methods function according to the same general principles, they rely on very different placement of the explosive charge within the forming chamber.
Standoff Method: With the Standoff Method, the explosive charge is used in conjunction with an intervening medium. In most hydroforming applications, the intervening material is typically water, oil, or air. The required deformation level dictates how far the explosive charge is placed from the piece of metal to be formed. When the charge detonates, the ensuing force is transmitted through the fluid and pressures the metal into the die. Detonations used in the Standoff Method can often reach several thousand pounds per square inch (psi).
Contact Method: In the Contact Method, an explosive charge is placed in direct contact with the forming metal. This process generates far more pressure than the more conventional Standoff Method. By placing the explosive charge in close proximity to the surface material, the detonation can result in as much as several million psi.

"What happened was the hydraulic fluid hose broke and the fluid went near the exhaust and caught on fire the driver was OK. He used a fire extinguisher to put the fire out. I stopped recording after he jumped out of the truck." - guy that filmed it

Timelapse of a giant excavator moving to a parking site
Hydraulics lift the assembly, and then slides it forward to set it on the ground. Then the base lifts up and slides forward and then lowers again to lift and slide the assembly forward again. Repeat. The interior view shows the movement. Sort of like a ratchet.
@newtboy can probably explain in fewer words.
I see it moving, but HOW is it moving?
A-10 Thunderbolt II Brrrrrtt Compilation
It's the A-10's gun firing at 4200 rounds per minute, 70 per second:
The General Electric GAU-8/A Avenger is a 30mm hydraulically driven seven-barrel Gatling-type cannon that is typically mounted to the United States Air Force's Fairchild Republic A-10 Thunderbolt II. It is capable of firing 4,200 rounds per minute.
Here is a gun test of the system:

Cool, but what's the "BRRRRT" noise about?
Water Wheels Can Pump Water Over A Mile Without Electricity
So, the maximum hydraulic pressure head (lift) would be to the same height as the top of the wheel?
Or is there a more subtle engineering take on this?
Recovery team colossal fail
Silly mistake on the rearward's operator. Should have use the hydraulics on the boom and not the winch.
