Production and other realities aside, I've seen some cool shit in my life and this demo is high up there! Did you guys catch 0.5 mach target top speed? That's 600kmh. It'd better do that flying because there probably aren't any rubber tyres that could endure that before exploding within seconds.

BYD has made the more practical cousin of this, and you can actually buy it. They have a car which jumps over potholes automatically: https://www.youtube.com/watch?v=zIKAn8yDkpA

Some cars, if you have to ask what it costs, you can't afford it.

Other cars, if you have to ask where the government will allow you to drive it, you can't afford it.

Anyone know the physics of mach diamonds purely from compressed gas? I'm not a physicist, but I thought one of the key aspects of compressed gas is that it can't expand faster than the speed of sound in that gas -- the speed of sound is literally the limit to how fast it can expand?

Original roadster is one of the best looking car designs for my taste. This... subdivision modifier over the Cybertruck.

Did anyone else feel like Elon and the execs just didn’t really even bother trying with the presentation? The car is a unique and incredible achievement so on the one hand, they’ve earned the right to embarrassing-divorced-dad gas-station-flowers it during the reveal presentation. Maybe they could have been even sloppier, and literally just a-whooped and a-hollered and shouted “this is cool as fuck!” and it would’ve been just as fine.

Part of me though wonders what this would have been like if it had been a slick sciencey presentation that paid real tribute to the talent below the smug denim C-suite. A bit more Engelbart or Feynman or Sagan and a bit less Balmer, Bezos, and Bozo the clown.

Showing the world your flying car is a moment to shine as a serious person. These men seem to be actively trying to not do that!

One interesting idea for this technology is to prevent accidents. Imagine you are about to get hit head-on by a drunk driver. If only you had a set of thrusters to lift your car at the last second. So basically use this a crash collision avoidance "before" your airbag has to go off.

I genuinely didn't believe they'd ever do more than use cold gas thrusters for a lame boost effect, if at all. Happy to admit I was wrong, that was cool.

(still not buying a tesla thooughbeit)

Did the car technically fly? To me it seemed more like a controlled graceful landing. Would we technically call that flying?

Cool marketing gimmick. The suction is cool though, let’s see how it will do on the track. Basically your own Brabham BT46, very cool

When I first saw the car slowly invert and stay inverted on the ramp...."what the heck am I looking at exactly?"

Amazing suction power. Waiting to see a video of its crazy turning power.

I guess that puts the final nail in the coffin of the 2019 Roadster that was announced but never arrived. Shame, because I loved how it looked. Some of its aesthetic lives on in the Highland Model 3 at least.

procflora • today at 8:26 PM

Assuming this never really ships (ahem), this is basically an upper-tier "YouTuber engineer" stunt video with a NASDAQ symbol attached. And the results there seem to suggest that Musk's marketing schtick is wearing a bit thin...

I like the spirit

sometimes u gotta just ignore economics and instead make history!

bluSCALE4 • today at 9:08 PM

I personally see this like a 1UP for rich idiots that are about to drive themselves into oblivion. Beats the solution in Demolition Man.

If this turns out to be real, I am happy purely on the basis of innovation.

This is not and will probably never be practical, but it's something that's never really been done before, and for that alone I kinda like it.

tills13 • today at 8:42 PM

I can't wait for them to never actually produce this or, if I'm wrong and they do, I can't wait for someone to seriously injure themselves or someone else.

Genuinely impressed, incredible demo

AlfredBarnes • today at 4:54 PM

What happened to the last one they announced? Is it just gone? are the preorders carried over?

So has he hired anyone who does not exist to champion the cause of the innocent and helpless in a world of criminals who operate above the law?

Been a while since I was impressed with a tech presentation. I was waiting for a clear case of AI assisted movement ( though I personally expected to see it for the first time in a military chopper ).

**

Side note, as I was looking for the right stream, youtube gave me a link to a different deep fake 'Musk' stream where he extolled virtues of sending him money ( https://roadster-tesla.com/#participate ). Everything has changed man. I am sure the scammer actually got some people.

chung8123 • today at 6:18 PM

As Elon intermingles the company how are investors compensated fairly for this. What does Telsa pay SpaceX for the technology and is there a conflict of interest?

Ok, it's cool. Now, why Musk betrayed Ukraine?

thedangler • today at 9:01 PM

How did they get it to stick to the track just hanging there. It didn’t look real at all.

Grombobulous • today at 4:42 AM

As Doug DeMuro would say, this is a “rich guy go fast” car.

Is it going to be fun and engaging to drive? Absolutely not. It doesn’t even have a steering wheel.

Finally, a vehicle that’s perfect for the CEO in your life who wants to upload his brain to a data center powered by the body heat of his employees hooked up to the pods from The Matrix.

The reality of EVs is that they all provide more or less identical driving experience - immense amounts of speed in straight lines and pure control around corners. But you can't really make something nimble or chuckable when it weighs 1.5 tons.

(Calling it a "roadster" is cute, but this has nothing in common with a Boxster or Miata. If anything, the ICE analogue would be muscle cars.)

Because there are no real unique driving characteristics, the only engineering you can compete with is raw speed or price. That and crazy gimmicks.

Wondering how loud this would be if you were in the driver's seat or, worse, standing nearby.

feverzsj • today at 5:05 AM

Maybe the most useless feature for a car. I'd imagine you need some commercial performance license to actually own this feature.

This car shouldn't be considered just a car. From now on, automotive technology will be used in completely different ways. For example, off-road jeeps may no longer need to cross water.

prometheus1992 • today at 7:54 PM

This is a showpiece at this point. but I can see these on the roads in ~10 years; but it felt more like a frog car than a flying car? in my mind flying quadcopters felt much safer in videos than this frog. It feels overly complicated based on what i have read; rocket boosters?? why? quadcopters and other flying taxis seem much more economical and using tech that's been reliable for at least last 20 years.

GodelNumbering • today at 8:34 PM

'Thrust' version takes $245,000 of downpayment (not the flying version that is 'invite only'). That money is neither escrowed nor earns an interest.

With high interest rate and tight money supply, this could get them a few billion dollars of 'customer financing'.

george_max • today at 2:50 AM

This is an incredible feat of engineering. I have my doubts of the 2028 mass production timeline, but I am quite amazed.

etothet • today at 2:53 AM

I watched the ~16 minute presentation on YouTube and it was as if Elon and the two other guys presenting were doing a skit at a talent show. They seemed extremely unprepared. Maybe they were intentionally trying to come across as off the cuff, but it felt unnatural and cringey. Together they have the charisma of a paper clip. These guys are so full of themselves that it’s difficult to appreciate whatever accomplishment this may or may not be. And, of course, no way it will be street legal with air thrusters. What a complete joke.

This will never be allowed to be anywhere near a road I hope.

amelius • today at 8:09 PM

Probably among the least comfortable cars to be hit by as a pedestrian or cyclist.

CommPhD • today at 3:56 PM

If used on public streets, these thrusters could easily maim/kill people- reckless to include them on a car.

1: That's an amazing demo, just fantastic. That makes me happy

2: I still want a topless Tesla that could be a good daily driver; an SL63 competitor basically. So, I'm sad.

It should have been a Delorean.... Still cool though

coef2 • today at 8:17 PM

Good for a date I suppose. It has the suspension bridge effect.
