In Planes, where there are 3 or more levels of redundant power and hydraulic systems with an ability to fail down to a limited mechanical operation mode if all the other backup systems fail. It's proven because they designed it with a stupid level of failsafes.
There's no redundant power in the Tesla Drive By Wire system, if the power is cut, you lose the ability to steer. You've got brakes, but you're without any of the assistance that the car normally provides. It's so fucking stupid I can't believe it's allowed on the road. If anything goes wrong that cuts power while you're in motion, you're suddenly captive in 3.3 tons of stainless steel without crumple zones, without the ability to steer, with naught but your unaided foot on the brake peddle to determine your outcome. It's nothing like the multiple layers of failures you'd have to endure to find yourself in trouble in a plane both for the power and the hydraulics.
Oh the Cybertruck is an absolute Deathtrap.
First off, the wire control systems in aircraft are absolutely reliable, in part, yes, because of the backups and redundancies. I figured I didn't need to say that.
Because the cybertruck is much worse than you know, based on what you wrote about things going wrong.
You know how sane design has different systems with their own cable bundles, so that if one bundle is damaged, you lose that system, not Everything dead?
Well the Cybertruck puts everything in one singular bundle. If that gets damaged, everything electronic dies. Which can include your backup mirror.
In short: wire control systems, with redundancies, great, long overdue. Cybertruck pos.
Not even that, with modern brakes being electrically enhanced, they are sometimes almost unpressable when the power is cut. Try turning the ignition off while still rolling and see how hard it gets (may depend on model/brand)
Very true. Perhaps my statement which continued on beyond what you quoted didn't make it clear, but I did point out what you said: "You've got brakes, but you're without any of the assistance that the car normally provides" as well as stating later that you've got "naught but your unaided foot on the brake peddle" both of which were intended to say that it's pretty hard to brake in most cars these days without power brakes.
I don't know how the Cybertruck breaks down on the easy <-> difficult manual braking spectrum, but I imagine that given the high gross vehicle weight and large wheels, it probably steers more towards the difficult end of the spectrum than the easy. Such a dumpster fire of a vehicle.
Ah ok. I assumed you meant stuff like assistance systems. I think you're right about the break resistance of this thing. It weighs 3 fuckting tons (over 6k lbs), this thing will not be stoppable by muscle power alone. I am so glad, that there is no chance of ever meeting one in my country
Lucky 😆
