        I can hear him saying, “of course it will be fine” with a tone that implies questioning the fineness was the stupidest thing he’s ever heard, because he thinks projecting confidence works for anything just like it works for tricking people that he knows things he really doesn’t.

        And then there’s a good chance he acts like there was no way anyone could see the result coming once it’s clear that it isn’t, in fact, fine.

    A wave od horror washing over me as I realize these idiots can afford a Cybertruck while I can only have an old beater.

      wealth and stupidity come hand in hand in many, many cases.

      I think this is partially because in order to make a lot of money in most cases you have to fuck someone else over and never have it occur to you thats what you’re doing. Like if you find out you can buy t-shirts for €1, then you go to your neighbor and tell them they can have a t-shirt for the low price of €30 (and manage not to feel bad about that) you’re a successful businessman and a pilliar of the community.

        And if you can get someone to even do the part of finding the $1 t-shirts for another $1 instead of you doing any work, you are a job creator.

    Since no one else has said it, this isn’t a design flaw of the truck. The operator didn’t let air out of their tires. Before driving on sand you really want to let your tire PSI down to like 15 to be safe. I used to pull hummers out of the beach with my old four cylinder Nissan pickup because their drivers were often overconfident they didn’t need to deflate their tires (or just completely unaware). I don’t like Tesla but this is an operator error, not a fatal flaw of the truck.

      It’s more of the taking $150k truck that doesn’t like sand, salt, or water to the beach.

      You aren’t wrong though

      I used to race cars, and would over/ under inflate my tires based on the weather and track conditions. Never thought about driving on sand, but that’s a super useful tip that I would wager most people have never heard.

        It’s not just sand, rock crawlers will deflate tires down to single digits (that’s why they use beadlocks) so that the tires actually wrap around the rocks.

          I guess you’re talking about psi.

          (No offense to you, dear Buffaloaf, I just looked it up and thought I might share).

          For everyone of the 191 non-USA countries, 10 psi is 0,69 bar or 690 hPa. That’s pretty low.

          By the way, why is psi written in such a weird way? It should be lbs/ in^2

            Because in^2 is generally said “square inches.”

            So it’s “pounds per square inch.”

            Sometimes “per” will get its own letter, like in PPM - parts per million - and sometimes it’s left off, as in PSI.

              Thanks, friend :)

              I know how it comes to be, I just think it’s stupid.

              For example, kW times h is not the same as kW per hour. That’s why kWh means kilowatt times hour.

              If I wrote ms to denote meters per second that would create massive confusion.

                Wait wait Wait, can you give me more on this kWh thing? I thought I understood this already.

                A single kW is a unit of power, literally 1000 watts.

                A kWh is a unit of energy, as in stored or delivered. Draw 500 watts for 2 hours? That’s a kWh. Or have a battery that can hold 1 kWh, then assuming 100% efficiency you could draw 1000 watts from it for an hour before it was empty.

                All of this is kW times hour, I would say? But in my mind I would interchangeably say per hour as well, they feel the same.

                Obviously I’m wrong, but I’d like to know why lol

                  If you use exactly 20 kW for an hour, it will translate to 20 kWh. But if your power usage varies over time, you can’t keep track of it so simple. It’s just how it is.

                  The unit is really watt [W] and the Greek prefix kilo (k) for 1000. This way it’s fast and easy to convert to different scales (like Mega, Giga etc) for comparing numbers

                  A watt is a derived unit for a rate of change, an amount of energy used in a unit of time, so P = E / t. A kW per hour would be a rate divided by time, or E / t^2, resulting in another rate.

                  More colloquially, think of watts/power by analogy to another rate, that of speed. Moving at a speed of 100kph for 3 hours results in 300 speed-hours of distance. Saying 100 kilometers per hour per 3 hours sounds awkward, but is actually a weird way to say acceleration, a rate of change of speed. (And probably a hint to get your car serviced.)

                  Anyway, the key is to think of a kilowatt as a rate, not a quantity.

        i mean yeah, but like. You can literally dig it out in most cases. Regardless of that fact, airing down tires is a good idea, though im sure the tire deco would’ve mauled the tires in this instance. And sharp turns is just a bad fucking idea.

          This thing is like 6600 lbs, and on what look like street tires. Airing down would be great, before this was highcentered. I am also not so keen on getting under that to dig it out.

            6600 lbs is a fuckton of weight to be moving around off road in situations with soft ground where tires might sink into loose sediment/mud. It just doesn’t make sense to build an offroad vehicle at that weight level unless you are only ever going to drive on rolling dirt forest service roads or on wide open arid and extremely firm terrain.

            Yeah I know a big chunk of that is the battery, but that is the problem, if you want to design an actually capable electric offroad vehicle I think you need to start from the design standpoint that the platform needs to prioritize being lightweight, which directly points to a small old school wrangler type vehicle or to committing to a solution like the newest AWD toyota siennas that most efficiently makes use of the design constraints of having a large flat battery running along the base of the vehicle. I mean even those only weight 4800 lbs (though they are a hybrid not a dedicated EV and the battery isn’t actually that big but you can imagine a similar vehicle with a much bigger one).

    What am I looking at? Should I conclude that Cybertruck is a bad off-road vehicle, or that sand is an unsuitable surface for driving, or both?

      Mostly that the driver is an absolute muppet. Sand like that is so soft you sink to your ankles walking in it, the truck never stood a chance.

      An F-150 weighs just over 4,000 pounds. A Cybertruck weighs nearly 7,000.

      That’s a lot of weight pushing into the soft sand.

        This isn’t true. Many higher trim F150s (bigger cab, 4wd, luxury interior) weigh over 6000lbs. Only the smallest, cheapest ones used for work vehicles are on the 4000lb range. Not defending the Cybertruck, but repeating false info doesn’t help.
