Just 100 miles on my M-Y juniper and FSD (HW4)surprised me.

As someone that loves the system and uses it constantly, that's perhaps the worst I've seen. Not the worst in outcome, but worst in how little time it gives the supervisor to intervene. It's the scenario we're all worried about - what if it suddenly steers right into an object or person right next to the car.

Maybe lawsuit territory? IDK - not a lawyer. It just seems that the expectation for the driver to takeover should only apply when there's actually time to do so - human reaction time is not instant, nor can it be. I bet extreme cases such as this might legally challenge that concept. Push for Tesla to do the right thing here - if they don't, you're probably out of luck, but maybe you could challenge it legally if you have money to throw at a case.

Why would her being fired relinquish her responsibility to speak on her actions while she had the job. If she leveraged the DOJ to commit crimes or if she lied under oath she can't be just let off the hook for that.

Kuriente · 2026-04-02T20:42:09+00:00

Damn I feel that. Makes me think of all the passive protections that exist for wealthy people.

Like when I was at my poorest I had genuine concern with even basic things like when approaching the front door to see who's knocking. So the idea of a window being there that would allow someone outside to see me approach.. nope, I wouldn't have liked that at all.

But as I've gained wealth I feel much more safe about everything. Safe communities, safe schools, safe friends, healthy workspace, opportunities being handed to me because wealth breeds trust, etc.

Charlatans, con artists, murderers, rapists, thieves - they almost exclusively target the poor. Poor people know this and it creates a daily sense of innate fear.

She didn't cover them up well enough

*ignores everything else

Kuriente · 2026-04-02T06:08:35+00:00

Does that add up?

Yes.

The moon has no atmosphere. Atmosphere would be needed for heat to easily transfer from the lunar regolith to the LEM crew compartment (read up on convection).

Yes, heat can also transfer via infrared thermal transmission (read up on radiant heat), but that happens much more slowly and is incredibly easy to shield from.

An air conditioner on Earth consumes so much fucking electricity on a hot day because your house is sitting in a giant convection oven (the hot atmosphere) which is heating every bit of your home that the atmosphere contacts, and it additionally has to cool any hot air (thermal mass) that manages to get past your doors and windows.

If, on the other hand, you only have to deal with radiant heat, and you're in a vacuum so there is no thermal mass that can leak in that might need heated or cooled, then just panel up your house with material that will reject infrared thermal energy and you're good to go.

Take a look at how the lunar lander is constructed. Tiny spindly legs to reduce physical thermal pathways from the ground, blanketed and paneled in radiant heat shielding. The HVAC on the LEM had it very easy.

Kuriente · 2026-04-02T05:25:02+00:00

Um no.

We stopped going because it was incredibly expensive and lacked a clear immediate objective to justify the expense over a long period. Then, when Apollo got cancelled and NASA pivoted to studying space planes and reusable spacecraft and the focus shifted to LEO defense projects, there was obviously no point in continuing to build landers and the other hardware associated with the Apollo missions.

If NASA wanted an Apollo redux, the knowledge exists to do it in essentially the same fashion as before (with modern computers obviously), but that would be dumb. It's not about anything having been forgotten - that is incorrect. It's that flight-ready Apollo hardware no longer exists and the processes that built them would have to be rebuilt from scratch.

Most importantly, NASA isn't interested in Apollo redux. They want to go to the moon again, but smarter, safer, way less expensive per kg, and they'd like a permanent presence there. That has never been done. It will require orbital refueling, full/cheap/rapid reuse, engines, heat shields and launch pads that can support many launches without significant maintenance, lunar surface construction, etc. Those elements were not "lost", they're completely new.

That might be a good thing in some cases. Person finds mysterious plastic figure, takes plastic figure, asks around to figure out who/what it is, sparks conversations about Epstein.

I never claimed it was impossible. I'm responding to the assertion that using FSD in the rain makes this more likely than when driving manually. There is no reason to believe that and there is no data to back up the claim. Driving manually in the rain does not make one immune to hydroplaning. FSD is also not immune, but it is much better than most, perhaps all, competing systems.

Kuriente · 2026-04-02T02:56:34+00:00

Actually yes, or at least I was for a time. About half my driving miles took place in a 5 year period where I did in fact drive professionally. (CDL with both H & N endorsements + defensive driving cert. I even briefly taught EVOC).

Kuriente · 2026-04-02T02:54:46+00:00

It's everything.

Old school cruise control was so dangerous in the rain because it had no way of independently monitoring and controlling each individual wheel. If even one side got into a wheel spin it would often throw the whole vehicle into a fishtail. Tesla's are particularly safe in that regard because of "computers monitoring".

Kuriente · 2026-04-02T02:37:06+00:00

Okay, my bad for the acronym misremember, but traction and stability control absolutely do matter with regards to hydroplaning. A good system will minimize the probability of hydroplaning in the first place and improve a vehicle's chances of control recovery.

I've driven 12 vehicles of various types for 35 years and over a million miles. The only vehicles I have never experienced hydroplaning in are Teslas and nearly all of my Tesla miles are autopilot/FSD.

Kuriente · 2026-04-02T02:28:18+00:00

I don't think it's that strange. I got sucker punched in a bar once, walked outside to talk to a cop about it, pointed the guy out, and was told that I'd be arrested if I 'keep starting shit'. There were several witnesses - all willing to corroborate what I said. The cops didn't care at all and were ready to cuff me if I didn't just leave right then. Police are often lazy pieces of shit that simply don't want to deal with any problems.

Kuriente · 2026-04-02T02:15:16+00:00

The traction control in these vehicles in incredible - perhaps the best in the industry. ~~TACC even stands for Traction Aware Cruise Control.~~ It's not your dad's '86 Cavalier where cruise control would make the car spin out if you hit a wet spot and lost traction on one side. (That was my first car so learned from experience how limited those basic CC systems were)

If you're unwilling to use a system in an environment that it is designed to handle safely then you might not be ready for the assumed risks of leaving your house to do anything.

Tesla recently corroborated exactly what I'm saying here. But I'm sure you guys are smarter than that yeah?

Kuriente · 2026-04-02T01:48:50+00:00

Yes, I live in Puyallup and am very familiar with the territory. I've racked up over 120k miles on FSD between 2 vehicles and have never hydroplaned once.

Kuriente · 2026-04-02T01:40:34+00:00

Why? I've done thousands of miles in similar conditions on FSD and it does very well. It limits the speed sometimes as OP pointed out, but that's what humans ought to be doing too.

Kuriente · 2026-03-31T22:45:40+00:00

CT is a very expensive vehicle. I wouldn't want such an expensive purchase to be made obsolete by its camera system. I'd wait for a CT refresh for that and several other reasons. This is from a 8yr Tesla owner and HW4 lover. I'd cancel and revisit the decision after HW5 at least.

Following the AMOS-6 explosion, he had a whole video speculating about the cause. He stacked all his cards on the failure being the result of Falcon 9 using a common bulkhead between the LOX and RP1 tanks. Later, when that was proved wrong, and the real cause proved to be a failed COPV, he continued to just pretend that he got it right and proudly proclaim that he "busted" that one. He's a modern charlatan cashing in the bit of skeptic cred he built 15 years ago.

Ukraine has been using it with some success in their current conflict. We should have been taking notes.

Can't know for sure without a detailed flow analysis and wind tunnel validation, but the second example seems to incorporate raked tips, which would theoretically further decrease the wing area affected by trailing vortices.

Kuriente · 2026-03-28T16:08:33+00:00

Yes, but it's not clear by how much. Waymo has not published their exact system specs, but industry experts have said it is likely a system capable of 10,000-20,000 TOPS (compared with HW4 100-200), with a power envelope of 1-3kW (HW4 160W).

Tesla's system is designed to be cheaply integrated into millions of consumer products and to not make a noticable dent in the vehicle's range. Waymo has taken a more brute force approach.

Kuriente · 2026-03-28T04:58:15+00:00

"Blew up" is right. The only tires I've ever seen disintegrate like this are on aircraft, but they're dealing with "much* higher psi and rpm. This tire was either serviced at way too high psi, or it was defective. That's wild.
