from an archive of the “Three dog day” Tesla blog post that’s now deleted. Took me a few to dig up, but I wanted the primary source for you.

“”” That was combined with upgrading the main pack contactor to use inconel (a high temperature space-grade superalloy) instead of steel, so that it remains springy under the heat of heavy current. The net result is that we can safely increase the max pack output from 1300 to 1500 Amps. What this results in is a 10% improvement in the 0 to 60 mph time to 2.8 secs and a quarter mile time of 10.9 secs. Time to 155 mph is improved even more, resulting in a 20% reduction. “””

You’re absolutely right and I clearly remembered this incorrectly. I conflated the model S actually breaking the NTHSA press that crushes cars to test rollover strength with the fact that the model s does use Inconel. My apologies. I wasn’t acting in bad faith, just remembered wrong.

They’ve wanted to shut down the s and x lines since the y and 3 were first being manufactured at scale. His timelines are always wrong but Elon has said this for years.

They shut down model x and s production to retool those Fremont lines for Optimus robots. They actually are making them btw. They’re using them in their own factories currently just like they used the Tesla semi for like two years for their own freight before selling them to the public.

Tesla’s machine vision research wing became xAI and the compute and resource were transferred over. SpaceX then bought cursor.ai, a small but goated frontier lab. They merged cursor with xAI and it’s now SpaceXAI. So each Tesla uses models trained by SpaceX AI.

The model s has always had Inconel in the frame for strength since relatively early on. But the Inconel came from SpaceX. Inconel is primarily used in aerospace applications. It made the frame of the model s so strong it broke the NTHSA machine used to test rollover strength. Look this up it is easy to verify.

SpaceX materials science has always been a big part of Tesla’s success since the very early beginning. Likewise inversely.

Teslas are some of the safest cars on the road. Even if you dislike musk (he’s not a good human), the record stands pretty solidly on their side.

When the NTHSA did the rollover test on the Tesla Model S, it broke the machine they use. It was estimated that it would take the weight of nine model S vehicles ontop of a model S for the roof to collapse. Tesla patented millimeter wave radars in the seats and got approval to install them. They now know if a large adult, small adult, child, animal, or groceries are in a seat. The airbags are reconfigured on the fly depending on what is in the seat. Consumer reports did a test and found Tesla wasn’t great in slam the brakes stopping distance, and did a report about it. Tesla confirmed and did some testing. They had a software update in less than a month to dramatically improve it to generally best in class. They have so many safety features many of which are now mandated in new vehicles that were not required when Tesla started producing vehicles.

Just look at some of the utterly insane Tesla crashes where in most cars all would he dead and folks walk away from them in the teslas. Some of the Teslas use a very special composite metal named Inconel in the frames. Look it up. Inconel is most commonly used in high performance aerospace applications like space rockets, and Tesla is the sole automotive manufacturer in the world with access to a large supply of it and know how. The Tesla model S plaid seats were designed to withstand 9Gs of lateral force, a thing no other street legal car in the world can do. Tesla asked the seat manufacturer that makes most all of the seats in the world to support this and they laughed at them. So Tesla made their own, and it’s safer than any of the other ones due to its design. Don’t trust me, verify this with google. It isn’t hard.

Pretty much precisely what the US did during the Cold War. To do so, we had to outspend the Soviets, and by a LOT. But the world buying US treasury bonds was basically a credit card for us to finance the above things that result into the world’s strongest military.

KREE!

Yeah, it is very good, but that’s only in roughly 1100 sq miles in the US. The long tail of edge cases is exponentially harder than the rest of it. They’re improving quite quickly was my point, and if anyone stands to pull it off, I’d bet on them pulling it off first.

As someone who’s owned a Tesla since 2018, and was part of the early beta program, I at least have a better understanding of the tech than most random folks who don’t actually drive one daily. Also, I’m not a fan of Elon at all.

It is easily one of the best if not the top three in the world (I’m including the Chinese companies like BYD, but we can’t get those in the US).

I can say “navigate to the closest publix”, it will back out of my garage, and then drive there the whole way hands off, find a parking spot, and park.

Tesla’s robotaxi sq mileage is roughly 1100 miles vs Waymo’s 475. This is true autonomous no safety driver in the car.

So jokes aside, Tesla is leagues ahead of everyone else sans maybe some of the state funded Chinese car brands. Having actually used the tech daily for years, it’s incredible, truly.

The US is ~263x larger than the Netherlands landmass wise. It would require a loooot more trains than we have or you have.

Buddy buy a Tesla, as that’s definitely gonna happen in the medium term.

Care to explain for those of us unaware?

Happily upvoting you for agreeing on principal with me. I shall likely join the flogging as a result.

I’m sure it will hurt my 11k internet point account.
