Unveiling the Tesla Roadster - 10-15-26 Livestream starts at 5:45 pm PST

Musk quotes regarding the Roadster:

“safety is not the main goal”

"if safety is your number one goal, do not buy the Roadster"

"[Tesla will] aspire not to kill anyone in this car".

And then there was this nugget from "TechCrunch":

“Every usable void in the car is packed with Carbon Fiber Overwrapped Pressure Vessels (COPVs),” Tesla wrote in a post on X, referring to the type of pressure vessel that has been at the root of multiple SpaceX rocket explosions [my emphasis].

And all with 300 miles of range.

So, yeah . . . .

They should share the test failure blooper reel for this one. Would be hilarious

It's on X. They shared a development video. I don't know if they technically shared any fails as they dropped a car and it exploded (maybe that was on purpose)

The difference is that this would be just using normal compressed air and unlike in a rocket, mass is less of an issue so you can make them more robust

I tried some reverse engineering of it, the carbon fiber tanks are existing aerospace tech, the compressors pumping them up are realistic pressures...Car is still likely going to need a step change in battery tech to get any range and lower weight to drive around without the rocket propulsion... The McMutry Spierling is quite a smaller car with a 1000 kg weight and 60 kwhr HV pack.

300 miles is the 2 seat variant and the rocket car has only one seat

I'd much rather have an Air Sapphire. It's a practical car that can actually be driven down the road, while still delivering more performance than I'll probably evem learn to properly handle. And I predict it'll turn out to be much more affordable to purchase.

Imagine the warranty, insurance on the roadster, it will also will be very heavy, extremely unreliable. Just another cybertruck like pet project. At least Musk can afford to throw money away.

I work with a lot of pressure vessels. At 350 bar, COPVs rupturing in a car would disintegrate you at a mere 1/4th of the energy of a titan sub implosion. Even without COPVs though, hypercars are death traps in most crash scenarios.
