A Tesla engineer said the test was done wrong because the frunk increases in pressure every time.

"You are holding it wrong!" 🤣

Of course it just keeps hitting harder when things are in the way.

Literally Tesla's response

I'm sure these "engineers" were confused everytime they saw an elevator door not mercilessly crush people.

This breakthrough technology could finally provide a way to teach people on the MTA not to hold the doors.

Nope, but they probably know that an elevator doors and a car lid are two completely different thing with different use cases and security concerns.

They sure did not know about the "not crushing human limbs" part.

Obviously.

But let's face it: if the car lid would never close if something is in the way, some other dumb youtuber would have made a video about it and here there would be a discussion about how stupid are the engineers to not let the lid close even if a bag in slightly on on the way and the user know what they are doing.

You're missing the point of a safety feature. The car shouldn't, by itself, close the lid if something's in the way. It should allow the user to push it down, or disable it temporarily, to do so.

The point of a safety feature in any system is to prevent unexpected situation from having unexpected consequences, not to be a magic solution that accommodate for brainless people. In one direction, you can make the judgement call and force the thing down, in the other direction you lose a finger.

I get the safety feature. The point is that here I am saying to the car to close the lid even if something is in the way. I made a conscious decision to do so, and more than one time, so I expect the car to do it. But I agree that it could have been designed in a better way.

Which is exactly what happened here. He made the judgement call to ignore the safety feature (and probably ignored how the feature works)

It that point why not just have some blades slide out on the third try?

Why bother when the door itself is an effective guillotine?

He did the test wrong because he's experimenting with "safety" algorithms that the manufacturer has provided little-to-no documentation on and is having to come up with answers on his own. Maybe he wouldn't be "doing it wrong" if Tesla hadn't over-engineered every aspect of their piece of shit truck in the first place. This thing is a solution in search of a problem, and it'll chop your fingers off until it finds it.

Most general question, what is the main purpose of this car? Why should people buy it?

It is a tank.

Steel walls for rich guys who want to protect their asses from masses of poor people around.

What should the door of your tank do if you want to close it, but some bonehead does not move his fingers out, repeatedly?

Now hurry, finally! This rich guy wants to get away from here! BAM!!

If it increases in pressure every time, I’m now curious how many times you need to close the trunk to cut a finger off

That was very nearly my exact same thought. Maybe not for curious children with carrot-sized fingers, but for adults, how convenient! Business competitor's body won't quite fit in your fancy frunk? Just while away on your phone for about 10 minutes, let the cat do its magic, and off go the legs! Travel-sized!

I wonder if you can get the frunk to critical velocity at the touch of a fly by constantly pumping it up like a pump action gun.

He forgot to turn on Finger Safe Mode™️ before closing the trunk

But this feature requires an extra monthly subscription, that wasn't included with the package of the YouTubers

They're gonna add this in and call it "Jeremy mode", just like the existing Joe Mode
