Elon isn't morally worse than my grandparents. It's currently much easier to rally people around things they hate than things they like or support. It seems like that was always true to a certain extent, but social media in particular has dialed it up to 11. Most of my coworkers and family define themselves by what they hate rather than what they like. I put a lot of effort into not going in that direction.

Did your grandparents buy a company and fire two-thirds of the empoyees, and then try to deny them severance?

Of course not. They never had the opportunity. If they had been born wealthy enough to treat companies like toys, they very well might have.

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…

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?

Everyone gets bigger cars because bigger cars have more room inside so they're really comfortable and practical. Teslas are heavier because they have to use batteries and batteries are incredibly inefficient compared to petrol. This is the consequence of you asking them to get rid of combustion.

If you've ever been in the cab of a recent F-150, you'd know that they don't have more interior space than a VW Golf. More practical, sure, but only if the one time per year you haul your boat out to a desert reservoir is worth the countless attempts at parking. Secondly, battery + motor is actually more efficient than ICE. You might be thinking of power density, which is significantly lower on an EV. Thirdly, I don'…

I have to call BS on the F-150 to Golf comparison. My 2018 Golf has nowhere near the interior space of an F-150. The Golf is (fairly) comfortable, but as a taller person, an F-150 is absolutely luxurious in leg/knee/head room compared to the Golf. It is like riding on a couch vs. being strapped into a race car. Not to mention that there is just about zero rear seat leg room in the Golf when adjusted to my driving position, while an F-150 my 90lb dog can stand on the floor of the vehicle back there.

Safety is not infinitely valuable

Sure but that's not an argument for letting the person who is putting others at risk, decide how much safety they want to pay for.

The statistical value of life in the US, which is applicable to small diffuse risks, is ~$10M. When the NHTSA or EPA or whatever decide whether to spend money on clean up a river to reduce cancer risks or impose safety rules, they use that amount (to first order). If someone is willing to pay p*$50M for a p<<1 chance of killing a member of the general public, the gov't can allow them and then spend that money saving lives, leading to both net lives saved and additional freedom/flexibility.

I would say that yes, at any given moment in time, the pedestrian is responsible for themselves if they want to stay safe. It's too late for any laws at that moment. You either notice the car isn't slowing down and avoid stepping out, or you do step out and hope for the best. Not a good way to stay alive.

No, all parties are responsible for traveling safely. If a vehicle wants to kill a pedestrian or bicyclist who is being careful, they can. It's very easy to do. And it's not too late to discuss laws, because I'm not a pedestrian right now. Again, it's a bad faith argument to pretend we don't have time to discuss laws when we're not walking in traffic.

If someone wants to kill a pedestrian, that's murder. Everything else is an accident due to negligence. You can keep going in circles saying the car is driver is responsible for this and that, but that's just relying on hope that they adhere to it.

If you want to increase the odds of not dying as a pedestrian, you need to be on the lookout. End of story. I'm from the SF area. There is no shortage of people that walk with their heads down in their phone with headphones, whole crossing intersections. IMO, they are waiting to die.

1. Isaacson's Musk biography was so poorly written and fawning I couldn't finish it. I take nothing in it as fact, mostly PR and hagiography. 2. Musk has had lots of plans. Plans that he dumps the minute he changes his mind.

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.

No, that’s not how any of this works

1kg of petrol/gasoline is ~48MJ. 1kg of Lithim-ion battery is ~0.25MJ/kg. Gasoline is ~192X energy dense compared to Lithium-ion batteries. Li-on is the most popular battery due to its cost and weight. In terms of weight: Tesla model Y = ~4,500 lbs. F-150 lightning = ~6,500 lbs. Rivian R1T = ~7,000 lbs. Hummer EV = ~9,000 lbs. ¯\_(ツ)_/¯ Cybertruck = ~5,400 lbs A human roughly weighs 160lbs (~72kg). Buying electric tr…

I say this very sparingly: this may be one of the worst "numbers-based" comments I've ever read on Hacker News. Typically, such comments don't leave out the critical fact: _you can't reuse gasoline like a battery_.

It's disappointing to see this. Is this kind of comment the result of activism? We typically do much better on HN.

VW won't warranty it (due to the suspension not tuned for it), but a Golf GTI can tow 2,000kg. So for many boats, you don't even need a stupid truck.

Had people wanted cars that are practical, they'd get minivans (and vans, if you do haul a lot).

Not to over analyze, but no matter if I'm on a bike or car I've always thought you shouldn't drive alongside or in the blindspot of another vehicle if you can avoid it (by a minute change in speed).

I'd rather be next to a car than behind a car, and ahead is always best. The issue arises when you don't speed (which I don't do).

What? Do you mean like way far ahead of them? So far, that you're not really in front of them?

How is that ever safer than being behind someone? You can control the following distance if you're behind someone. You can't make someone behind you pay attention or stop, and you can't make someone beside you not change lanes without looking. Why would you ever want to be in their direction of travel?

Seriously, please explain your logic on this. I'm flabbergasted.
