A though for the people doing the "boring" engineering at Tesla (like, you know, enhancing the range of the vehicles, improving security, making FSD closer to reality, etc...), who used to get some light (remember "battery day" ?), and are now on the backbench while the sycophants gets the budget for vanity projects like this. At least, at Tesla, the sycophants are _smart_ and pull out cool demos. Not the case in every "new clothes" kingdom.

Finally a vehicle for Bangalore!

Just curious: Was there a demo of a stable straight jump as well, or always barrel-rolls?

It must be incredibly difficult to keep the car stable while mid-air at low speeds, I suspect it wouldn't look that "elegant"...

I am amazed at how steady and in control the car was when flipping and jumping. If that kind of control on a vehicle is achieved today, it seems like flying car tech just took a giant lurch forward. Just in time for America's crumbling road infrastructure.

I hate Tesla for their politics, broken promises, and all the drama that we are all aware and tired of hearing about. That being said, that was the coolest damn thing I've ever seen a car do.

I don't think there's any doubt in anyone's mind that it'll never make production like this, but what I see as being demonstrated is a suborbital lander/off-world ground transport concept that can work in low gravity environments etc. This will aid autonomous delivery vehicles etc to be dropped from low orbit and find their own landing sites, and then drive to location.

I wonder how many maimed kerbals are stranded around the space X facility while testing this.

siwatanejo • yesterday at 3:28 AM

It seems it's not a convertible anymore? Which means it shouldn't be called a Roadster.

It's a cool demo and all but I can't help but feel like it's not that impressive considering these companies control such an absurd amount of capital and this is all they can do with it. A stunt for a launch showing off features that obviously won't be in any real product.

A lot of public funds go into these companies and it just feels like they are playing around with toys instead advancing humanity. I sometimes wonder if we are not allocating resources very efficiently.

Just don't press the button where you have wires over the road... or anything hanging over the road... like signs...Don't press the button when you are about to go into a tunnel... or inside the tunnel... Also, check your passengers have finished their shakes, coffee, and other liquids...

With such a powerful suction system, I can see this replacing street-sweeping trucks in a few years.

If I'm understanding this correctly, it uses the electric motor to compress air into large tanks? How much thrust could that generate (and for how long)? It'd be amazing to jump over East River or the Hudson.

Rebelgecko • yesterday at 1:43 AM

Is the copy grok's writing style? It feels inhuman but still more readable than Opus

mppm • yesterday at 3:59 PM

The inspiration from the F35 seems to be quite literal. Spent a lot of time and money making vertical takeoff happen, but forgot to give the vehicle any useful capability once it's actually in the air.

lofaszvanitt • yesterday at 9:39 PM

Elon should read Anti-Grav Unlimited. It's a good book, actually a very good book. We want that tech. Time to invent the antigravity rods. AI is here, sorry, SuperIntelligence is here, AGI is on the doorstep, just ask the SOTA models to figure it out.

mullingitover • yesterday at 2:04 AM

So this is a completely obvious scam, right? I don't see anyone else calling this out and I feel like I'm taking crazy pills.

The thing that they showed off isn't something that they could legally sell, it would basically be a bomb. Also, the battery pack that would go in the car would be so large that they couldn't do the stunts they showed in their drone vehicle.

Are we not calling an obvious stock pumping charade what it is out of some sense of politeness?

hmmmm. spacex-tesla merger signalling?

Nice Testarossa!

thatonetime • yesterday at 10:46 PM

I have to be honest, I am a bit dismayed and sad to see some many negative, hostile, demeaning, and minimizing comments about this announcement. It really makes me sad, because without big dreams a society will cease to grow. It seems that either thick ideological lenses or righteous this won't be mass produced optics won't let some of us here appreciate the incredible anymore. I found the flying car awe inspiring and it made me dream and appreciate the incredible feats of progress our civilisation is capable of. I for one welcome our God of demos of awesome tech and honestly fuck everyone else.

kateyan • yesterday at 7:24 PM

What a beautiful car!

CodeWriter23 • yesterday at 7:16 PM

The lack of imagination in this thread is appalling. Especially given this crowd.

simonebrunozzi • yesterday at 4:27 PM

Very impressive prototype. Certainly an attempt to disrupt a specific segment of the car industry - "race cars", or "sports cars", or whatever you want to call it.

A few considerations, just my own thoughts.

1) I would bet that the actual car shown in the demo weights less than what will eventually be sold to the public. I am not an expert, but the way in which the car reacted to the air boosts suggests a relatively "lightweight" vehicle. Plus, I would imagine perhaps a smaller battery (again, for demo purposes).

2) It is a nice "exercise" as a game, or an expensive hobby for billionaires. I doubt, as Elon hinted, that using these thrusters will be allowed on public roads. Perhaps just on circuits?

3) Overall, Elon said that Tesla's strategy will no longer be about cars, but about robots and AI, and then proceeds to show a car that will cost billions to develop, and might not be the commercial success that justifies the investment.

4) Twitter (now X), Tesla, SpaceX... things are moving, tricks are being shown, and who knows, perhaps next year everything will be merged under ElonX, and he will finally be happy.

adjejmxbdjdn • yesterday at 4:12 PM

Am I missing something? At what point did the car fly?

The thrusters were able to cushion a fall.

That seems useful in ruining the ending of Thelma and Louise, but isn’t really a flying car.

So where is FSD that has been promised since 2017?

Cool stunt car though

rickdeckard • yesterday at 5:27 AM

Was there any demo showing the car stabilized mid-air?

It appears like they always did a barrel-roll because the car is simply not stable after take-off...

dataking • yesterday at 1:48 AM

Rocket-inspired design hints at desire to merge Tesla and SpaceX?

verytrivial • yesterday at 6:12 PM

SpaceX have great inertial measurement units and cold gas thrusters. We get it. Musk remains a fascist and can keep his cars.

What's up with wheels not being round anymore? How is that supposed to work? I understand it for Formula 1, but for real world driving, it doesn't make any sense

I have no words. Its like Elon asked Grok where can I take my business, and it suggested combine rockets and cars.

TheAtomic • yesterday at 4:01 AM

Flies, or jumps?

Dunno. Looks like it jumps. Fying seems to require some degree of control over direction but I'm just a gravity-impaired bidep.

elAhmo • yesterday at 6:49 PM

Amazing demo.

Also amazing stupidity of people believing anything close to this will hit the streets. Lies and lies for a decade, and now after a flashy demo it is again "2028".

nalekberov • yesterday at 10:16 PM

oh man, this is so ugly.

DiabloD3 • yesterday at 9:31 AM

Given how Tesla's profitability nearly vanished due to Elon outing himself with the "roman salute", I don't see why he thinks his company will be around long enough to actually get this out the door.

I have no reason to believe this isn't another Deplorean.

vonneumannstan • yesterday at 8:24 PM

This is pure marketing fluff. No way in hell this would ever make it into a street legal car.

Totally thought this was AI when I first saw this.

Awesome technical demo (assuming these weren't prop cars). Painfully awkward presentation.
