LOL My first thought was SpaceX for sure but on 2nd thought, I'm not so sure.

Does literally going to the Moon make any business sense? I can think of lots of possibilities but I doubt any of them really make sense for where humanity is right now. Maybe he does mean TSLA.

Well NASA is planning to build a moon base this decade. SpaceX might be helping them with that, thus planning some moon missions soon?
 
The only reason someone might be concerned that Tesla is ditching radar is because they don't understand how quickly technology is progressing. Specifically, AI vision technology.


Or they are someone who actually understands that AI is not magic.

The best AI in the universe still can't make vision see through a solid object to what is beyond it like radar can, or make vision see through fog and snow that blocks visual wavelengths but not radar wavelengths.


They aren't removing the radar because AI has magically made the cameras capable of X-ray vision- it's because it's too hard to continue trying to integrate with the new 4D BEV vision system and they feel it's not worth the extra effort for the marginal additional info. See Prunesquallors reposted elon remarks on that.

That might well be the absolute right path to go down.

But we know for a fact FSD has gone down several wrong paths before (including in 2016 when Tesla and Elon loudly announced Radar was awesome and should be a primary sensor specifically because of its ability to provide data vision physically can not provide

They've now decided THAT was a wrong path they went down and are trying another thing.


Teslas willingness to do that is a major reason for their pace of innovation.... rather than, say, Waymo having spent 10+ years now going down the WE ARE SURE HYPERLOCALIZED MAPS AND LIDAR IS THE WAY and still only operating RTs in one tiny geofenced area.


But it also means you can't automagically assume each new path is FOR SURE THE RIGHEST BEST ONE, because it might not be.

Tesla is fine accepting that possibility- if it turns out wrong, they'll try something else.....

Some superbulls are... less fine accepting that possibility than Tesla themselves though.



I would like to hear karpathy talk about this or I bet @jimmy_d will be able to drop knowledge on the radar deletion. Right now I’m betting on negligible benefit over very competent vision. Still it’s the platoon function for caravan of autopilot that it seems would be the most useful for radar.... and close distance caravan may be years and years away and even then, perhaps ultrasonics are just as good.

James Douma already covered this in a video with Dave Lee.... where he told us the same thing I've said here.

LIDAR adds no value to a vision system.

Radar absolutely does add safety and value as a secondary sensor in conditions of low visibility and things like bouncing under cars but should only be used in the occasional situation like that- not as a primary sensor which should be vision.



Ok. So lets work with this. First, would a human be handle this better than the autopilot? Probably worse because of worse reaction time.

But the goal is many times safer than a human, not just "any" safer right?


So would radar help? Maybe.

I literally posted a video of it preventing a Tesla from crashing into another car at speed on a highway because the radar saw the stationary vehicle 2 cars ahead the cameras could not.

That's not theoretical like your math- it actually happened.

It's likely it has happened many times, though not every time did the driver save the video and spread it around the internet.

Now does it happen often "enough" to be worth preventing? Some would argue 'at all' is worth preventing- especially since it's using a sensor already on the car.


But both the suggested reasons for the change I cited from the other thread- And Elons own words in the tweets Prunesquallor quoted- essentially boil down to integrating radar with the new 4D/360 vision system is REALLY hard, and they don't consider the # of cases where it might make the car safer worth delaying further development to make radar integration work properly with it.


There's every chance that math is totally correct... if getting a much-safer-than-humans FSD out sooner means forgoing a theoretically-even-safer-but-they-have-no-idea-how-long-it-would-take-to-make-work FSD that keeps radar that might well be a tradeoff worth doing.... and if research on radar 4D integration gets better in the future they can always revisit.






Anyway I'd again point out there's an entire section of the forums specifically FSD related if folks genuinely want to get deeper into the weeds of why this isn't a case of "Cameras just do everything radar can thanks to AI!" which isn't factually correct versus why this still might be the CORRECT decision even though it's removing data the cameras can't fully replace.


Whole forum for it, with multiple threads getting into it, here:



. But your sentiment is not unlike that you will read about on non-Tesla forums.
Nothing to see here
A big nothing burger
Dumb idea no different than the subway

It's weird you'd quote my post where I specifically say having millions of additional people experience the cars adds a lot of value and then claim I said it was a dumb idea.

The text you quote cites 2 potentially significant value-adds for the company- both the exposure at all, and the fact it claims Tesla will be building a larger people-mover vehicle (the 16 person vehicle) yet somehow the only part you appear to have actually read was pointing out going 35 mph through a single-lane tunnel wasn't especially futuristic.



.
These same people also missed out on 700% gains last year and think Tesla should be valued at $50 and is just an auto company

Man, 100% wrong twice in the same post. At least you're consistent :)

I was joking about LIDAR, but thanks for dropping knowledge on Douma radar etc

Ok. So lets work with this. First, would a human be handle this better than the autopilot? Probably worse because of worse reaction time. So this probably happens pretty rare as humans are still allowed to drive... Second the truck is travelling at speed, lets say 70km/h and then hits a stationary car it for some reason didn’t see(it’s not a Tesla semi). Even if this was a perfectly elastic collision, we are probably talking about a 10:1 mass differentional that the kinetic energy will be distributed into will probably not decrease the speed very much, maybe from say 70km/h to 60km/h. See quick
View attachment 652579
(You can play around with the numbers here: Conservation of Momentum Calculator )

The autopilot should have no trouble with this small decrease in velocity of the truck in front.

And even if we hit the car-truck-carnage our speed differential with the car-truck-carnage would probably not be too many miles per hour, that this would be the difference between life an death.

So would radar help? Maybe. Would it save any lives in these situation? Probably not. Would the benefit of a better vision system outweight this? Maybe, Tesla probably are better at estimating this.

I think if you brainstorm more scenarios you will probably see similar results.
AND, as a human driver I was taught to off-center my car to the car in front of me so I can see a brake light of the car in front of my car, and to base my decisions more off of the situation in front of the car in front of me than the brake lights of the car in front of me. I have also learned through my life to gauge the driving style off the condition of the car and driver in front of me before I can witness their style. Such as proper running condition of the vehicle and if it has a "Hillary is my co-pilot" Bumper sticker. My truck has a "My Dog is Smarter Than your Honor Student" bumper sticker, make of that what you will.
I wonder how much FSD already does as to positioning the vehicle to optimize the sensors. I am sure it does to some extent. But does FSD read bumper stickers? Or recognize to give a car some additional space when they throw a beer can out from the driver's side?

All they need to do is have Elon tweet a few subtle taunts about how Austin factory going to come online before Berlin despite large head start.
Honesty, I bet if someone who actually has twitter followers some of these taunts, I bet Elon would retweet. I’m sure he has lots of German Twitter followers that don’t like being second place.
 
Man my skimming skills have gotten a good workout today ...(radar...vision))....skip
Certain topics, like the eight we’re experiencing now, do - on the surface - seem mundane at best. However, the participants reveal much about themselves, least of which their knowledge base and how deep down the rabbit hole they will go embracing their ignorance. It’s actually quite fascinating human behavior and it does help to reveal who can be ignored without risk of missing some key Tesla investing information, but more importantly who should not bring children into this world. 😉

Conversely of course, it also reveals those with intact grey matter of intelligent, sensible, logical et al function. That’s also helpful.

Isn’t moon supposed to be about proof of concept; a base built as a test run for Mars, also a refueling and supply depot, an opportunity for people to try out space before full commitment and a revenue stream in terms of ‘take a trip to the moon/vacation on the moon’.

May be Elon was referring to Radar maximum capacity when he mention "we were stuck in local maximum", may be there is no way to improve false positive with Radar.
