Not when you're trying to make an objective comparison with a small number of trials.

If the test was always exactly the same, designers could optimize the car design for that precise impact force at that precise point.

The ability to compare different cars is probably more important than preventing designers from sticking a five foot thick plate of metal on the precise diagonal of the crash test, which would be obvious. A major part of crash testing has to be the forces felt by the test dummy, so there's not a whole lot designers could do to reduce those forces in exactly one direction without also reducing them in other directions.

I got hit by a Nissan Titan: http://imgur.com/a/nIMOP#0

I can't get over how intact the interior is. Any injuries to you? What were the crash parameters? Speeds? Head-on? (Looks like it). Your car was a Subaru something or other?

2012 Subaru Impreza Premium.

I had a slight gash on my head that bled for a little bit, and I have a dislocated clavicle near my breast bone.

I was driving 20 Mph, taking a left turn, the Nissan Titan was doing (by the drivers accounts) 45 - 50 Mph. Practically head-on.

According to the fire department, police and EMT's that arrived on the scene it was a miracle how in-tact the interior was, and that I walked away from it. The insurance adjuster at first wouldn't believe me when I told him to start working up paperwork for totalled while also telling him I had walked away from it. He ended up later calling me while looking at my vehicle, and I quote, "Are you sure you are okay?"

The guy that towed my vehicle from the accident site was surprised to see me after I was released from the hospital looking for my keys (house keys are on the same key ring), he hadn't been told about my status by the cops or anyone, and had assumed I was in crit-condition in the hospital.

Subaru saved my life, and for that I am extremely happy.

Damn. Glad you're OK and thanks for sharing.

I swear the longer I drive the more freaked I get by it, even with all the tech a well-designed vehicle can wrap you in.

While that's true, I don't think it's what the parent meant. Colloquially, when we say to boil water we don't mean until the vessel is dry , just until a roiling boil is reached (this is typically how we cook pasta).

If the 1000 kg is heated uniformly, this is not enough energy to bring it to a "roiling boil". There will be no bubbles.

Right. It's a good thing stoves/ranges heat from the bottom!

Hi there. Go ahead and watch this video from Tesla about how to cut someone out of a Tesla. The very first step is to cut the circuit like you say, but there are a few things you overlooked. Much of the video is concerned with instructing responders how to cut around components that may remain electrified such as the converter and capacitors which, in Tesla's own words, present a "serious hazard of shock" because "th…

Nitpicking, I know, but releasing 400 volts means nothing. Current kills, tension does not. It all hinges on the internal resistance of the power source.

Voltage means A LOT. A regular 12V car battery is a perfect proof: it has enough current to kill you, but at only 12V it doesn't overcome your body's resistance much under most circumstances.

400V can overcome your body's resistance no problem. And obviously an EV has a crap ton of amperage as well.

You're forgetting convection.
