Was Google's 20 percent time a waste of its talent?

This looks like a genuinely fun project to have worked on. That can be the difference between a top engineer burning out and staying motivated.

At a time when Tesla is struggling to make sales? I agree it's an impressive demo, but it has zero practical value. EVs were supposed to help the environment, not make very brief flights. Would this be under control of the driver? Should be part of the autopilot, maybe for collision avoidance?

This is in the same category as the Tesla flamethrower or the Teslaquila.

> it has zero practical value

After Cybertruck and the LARPing as a humanoid-robotics company, I was genuinely unsure if Tesla still had top-tier engineering talent. This shows otherwise. Maybe some of these improvements will trickle down to the Models Y and 3.

(It also looks like a lot of SpaceX engineering. I could see folks there wanting to take a break, particularly if this happened while the pad was busted.)

reply
You have not addressed the main point - this has zero practical value. No this will not trickle down to Y or 3, how would it? What possible use would this have? It’s a silly expensive gimmick.

Also, I imagine the cold gas thrusters and control software are all from spacex, this is what starship uses to orient itself in the air.

You’re that confident none of the materials or techniques aerospace engineers used to lighten this car are relevant to the rest of the lineup?

Not really, it uses grid fins and gimbals. The closest cold gas comes to air on Starship is in the upper atmosphere.

reply
No, both F9 and Super Heavy have cold gas thrusters - you can see them firing in onboard videos during the landings to orient them for re-entry.
reply
Yes, confident none of this belongs in a budget car. It’s not even useful in the roadster, it’s a gimmick, not flying but falling in a controlled way.

Nice pedantry on the thrusters in air, but I imagine the software here to orient the car quickly using thrusters was borrowed from spacex, the thrusters certainly were.

Again, none of this has a practical application - it’s like the flamethrowers- Elon thought it would be cool, so they made it.

Tesla's marketing budget is something close to $0. Stuff like this is why.

A flying car is a lot more valuable to the Tesla brand than some Super Bowl ads

Come on. They literally sent a car into space.

reply
Nobody would launch an actual payload on the initial flight, and they had to do 3 successful launches to satisfy the USAF´s NSSL requirements before they could launch very profitable payloads for them.

The Roadster was Musks personal vehicle, so Tesla didn't pay for that either.

reply
Even if I give you the benefit of the doubt and accept your statement as true, who cares?

Telsa board doesn’t, they need moonshots to justify their valuation. Elon doesn’t care, the engineers sure as shit don’t.

Maybe a midline quality control and reliability person? That’s not likely where many of the engineers for this project came from though.

reply
Yeah, wouldn’t they rather be doing real impactful engineering work, like figuring out means to display even more ads on personal user devices, maximizing the number of hours kids spend doom-scrolling per day, or making robots that are deliberately designed to take jobs away from as many workers as possible?

But, imagine instead being an engineer of any kind today and you’re only getting paid to work on boring things like advanced automotive technology and building cars that can maneuver themselves in midair and might possibly fly in the future? Ridiculous.

(This message should not be taken as support for Musk or any of his views or business ventures.)

reply
the pursuit of perfection should not always require justification :)
reply
I don't think so. The engineering behind an F1 car is not relevant to those buying consumer cars, but it helps sell them regardless.
reply
You must be miserable in your job. All the good engineers I know would gladly take some pay cut to be able to do projects like this.
reply
They learned a lot, and pushed their tools further, in ways that left them with new insights and possible engineering paths for more practical work.

“Play” “fun”, curiosity” and “challenge for challenges sake” are adaptive strategies for learning unexpectedly useful things.

reply
Imagine how boring the world would be if we refused every idea that didn't have an immediately practical purpose. Rocketry was probably overkill here but it did achieve at least one thing for the Tesla and SpaceX engineers: you can do things you did not believe were possible.
reply
It does bring up the question of what’s left in car design.

RAM jets?

A car could get 10–30% better energy efficiency than a conventional car at the same speed. Initially, the air jets would reduce and then eliminate wheel drag, and then hold for safety maneuvers. At speed, off-wheel-lift would be generated aerodynamically, with the option to also spot redirect air pressure from the RAM jet, or the air jets.

Then 2.0 would be the fully redesigned one-eyed two-seated flying Tesla Bodywingster.

All for the environment!

They learned a lot about technology fundamentally useless in cars.
