I thought it portrayed Musk's flaws pretty vividly, but I guess if you started out convinced that Musk is a terrible human being with no redeeming qualities whatsoever, it would seem like fawning hagiography by comparison. In any case, it was widely believed in the investor community that the Mexico plant was where the next-gen vehicle would be produced. I don't think California was ever really considered.

Well, the "investor community" wasn't really well informed. Tesla wanted to pull out of California due to regulations, and was only considering Texas and Oklahoma for the CyberFridge. Texas was selected the year after the initial CyberFridge announcement. https://www.theverge.com/2020/7/22/21334860/tesla-cybertruck...

Ok but what I said above was "the reason they moved the new production line for the next-gen vehicle to Austin." The next-gen vehicle isn't Cybertruck, it's the forthcoming $25K car. That's what people expected would be built in Mexico.

(But based on "Cyberfridge" I can see this conversation isn't going to go anywhere productive, so I'll just wish you a nice weekend. Throw in a last word if you want.)

While I appreciate the unique design of the Cybertruck, I have a huge concern with its huge size and the potential safety risks for pedestrians. The trend of increasingly larger vehicles, like SUVs and trucks, has already raised issues regarding pedestrian safety. The Cybertruck, being notably larger than most contemporary cars in the same category, could exacerbate this problem, especially if it opens the door to si…

My mazda has absolutely HUGE a-pillars, which are, in my opinion, a far larger threat to pedestrians, than having a simply larger vehicle. Like you can fit a family of 4 with a stroller in mine, I find myself leaning way forward to check that blind spot every time I turn right. And even that is second fiddle to people using their phones while driving, which is an absolute plague in general, not just for pedestrian sa…

Leaning forward to check the blind spot it’s how my driving instructor taught me to turn in a ca 2000 VW Golf.

Most EVs weigh about that much, to the point that some cities are considering amending "No trucks" signs to also say no EVs.

Tesla 3 - up to 4065. Tesla S - up to 4941. Tesla X - up to 5531. Tesla Y - up to 4416. Chevy Bolt - 3563. Leaf - up to 3853. Mach-E - up to 4920. ID.4 - up to 4848. E-Tron - up to 5754. BMW iX - up to 5659. Taycan - up to 5121 Kona EV - up to 3715.

I like how you just excluded all the comparable EVs. Here they are for completeness, most coming close to or topping out the standard 7k where they will post "No Trucks" signs.

   Ford Lightning - 6,893
   Hummer EV - 9,063
   Rivian R1T - 7,148
   Lordstown Endurance - 6,450
   Chevrolet Silverado EV - 8,532
   RAM 1500 REV - est. 7,500
   Alpha Wolf - 7,088

It is the single biggest step backwards in automotive safety in the last ten years. https://www.travelers.com/resources/auto/safe-driving/how-cr...

Are you claiming the Cybertruck doesn’t have a crumple zone? That doesn’t make a lot sense. The entire front hood area is hollow, there isn’t even an engine there. Just because Elon used a bunch of puffery to play up the exoskeleton doesn’t mean it acts like a boulder when it hits another vehicle. Crumple zones aren’t even relevant to pedestrian crashes.

The outer skin is made of 3mm cold rolled stainless steel, likely the same 300 grade alloy that SpaceX developed. A conservative estimate for the yield strength (based on similar alloys) is 275 MPa, or roughly 1.8x the pressure required to compress a human bone (150 MPa).

Normal automotive skin by comparison is made from 0.65mm steel or aluminum.

Are these charts simply displaying the gradual decline in children-under-13 walking and riding bicycles?

The chart shows child pedestrian deaths went from 1632 to 144. So a tenfold decrease. No idea about the stats on child pedestrianship but I’d be surprised if it was down 10 fold.

Why would you be surprised? Even in my lifetime the number of kids you see out and about has decreased dramatically, there's both a lot less to do outside and a lot more to do inside.

"they open fully in really tight spots where normal doors wouldn’t" I don't see how this helps. They're on the back, not the front, so the driver can't get any benefit. So you still always need to have room to open the doors normally.

Gotta put yourself in the shoes of a parent here. If you’re retrieving a child from the back seat, or are letting kids open the door themselves… you want something that is unlikely or basically impossible to smash into a neighboring car. Children aren’t careful, and if you’re trying to wrangle one in or out, you don’t want to also have to deal with the door. The front door you can control yourself, it’s not an issue.

Which is why mini-vans have sliding doors.

People bring this up a lot on Hacker News, but AEB (Automated Emergency Braking) is essentially standard at this point [0] on new vehicles (technically NHTSA just makes recommendations on this right now, but as a practical matter OEM's comply because someday soon it'll be mandatory without an explicit waiver). Between the forward-facing camera (usually running some version of Mobileye EyeQ) and forward-facing radar,…

Are people going to be using the front camera whilst driving and is that even a good idea?

Elon invented a car that can't hit pedestrians! Everybody please clap.

Except... you can recharge a lithium-ion battery many, many times before you have to replace it. You get to use gasoline one time. The absolute best efficiency of a gasoline engine is somewhere around 40% efficiency, with most being a lot lower. So your 48MJ number is a lot closer to ~19MJ. So, assuming you can recharge a lithium battery 100 times (most are going to be capable of many times that), you're break even i…

In your metaphor the battery would be akin to the gas tank though, rather than the gasoline that fills the tank. I think my gas tank can be emptied and filled more times than a battery and it doesn't lose capacity the more it's used or when it's cold out!

All my cars had worse mileage in winter.

> “I'll sit in a blind spot on a motorcycle happily, if there’s no other traffic…” Because you believe the driver has no incentive to change lanes, and so there is low probability they will change lanes unexpectedly?

Because I can brake fast enough if they do change lanes. I tend to pass, but if we're going around the same speed it doesn't bother me.

Huh. I figure it the other way. If the traffic is light, then people think they're the only person on the road. I expect they will change lanes without thinking or looking (Like, _Why would someone be in my blind spot with all of this space?_)

Whereas, when there's heavier traffic, you can't help being in someone's blind spot. In this case, I will usually speed up to being at least next to them, so I'm sure they can see me, and then I'll let the driver pass me, so the last idea they have is, _I just passed that moto/where is that moto I just passed?_

Overall, being in someone's blind spot is by definition, risky. And it serves no purpose, and has a clear remedy. Whatever. Ride you ride.

Good luck. Keep your head up.

Not enough for me to notice. I have a route that I can barely do twice without filling up be it summer or winter.
