  • The government is too risk adverse to take the massive long shots that the private companies can take, and would have to answer to their constituents on all the failures.

    NASA would never try to make something like Starship. The world didn’t even think you could make a properly re-usable first stage rocket.

    They would inherit the existing technology, and then slowly flatline back to their current state of operation.

    Edit: Just to further make the point - SpaceX isn’t just trying to make a reusable rocket with starship, they’re already building a massive production line under the assumption it’s going to work. They want to make up to a 1000 of these a year and are building towards that already. Go try and pitch that to congress for funding.









  • I’ve only done it once, but I got saved by being on a hill while parking. I had wanted the hill to let me roll back a little bit and I was going to stop it with the brake, but instead I lurched forward because I hit the accelerator. Given I was on a hill though my mistake had to work against the uphill and I didn’t jump up to far before I took my foot off, rolled back a little, and properly braked. It was very strange and confusing in the moment.

    I’d be curious how often this happens with basic cruise control on the highways, but (edit: I suspect) highways are more forgiving to the mistake than with something like FSD on windy neighbourhood streets.


  • Tesla says they overrode the self driving system.

    “Pedal fully pressed in the FSD crash. It was fairly obvious to anyone that uses FSD it does not drive like that.”

    Ashok from Tesla: “Yup. In this case, the driver manually overrode self-driving by pressing the accelerator all the way to 100% of the accel pedal in this residential area. They reached a speed of 73 mph during the crash, and had the accelerator pressed even after the crash.”

    edit: My guess, he wanted disengage the system so he went to press the brake, but pressed the accelerator by mistake instead. When it didn’t stop / disengage as expected, as is always the case in these types of situations, he pressed it harder because he was sure he pressed the right pedal. At that point he probably starts yanking on the steering wheel, or the turns were too tight for that speed. I’m sure we’ll get more details later when the full report is done.




  • I think people might see that sometimes, but not understand why, because they just see a starship blows up headlines and don’t understand what is happening as it’s a test program (for now), and the headlines / stories don’t convey that.

    So when things explode, sometimes it’s fine, and the stock might go up because a lot of really important things still were tested, some for the first time, and they went well.

    Other times, things will explode and it can cause huge delays, and while they learn something, it’s still ‘bad’ compared to the above blow ups, and the stock will very likely go down when these ones happen.

    And then sometimes, something goes wrong on the test pad and you blow it up, and that is very bad. It’s a test pad, its meant for that, but it causes huuuuuge delays.

    But OP is right, they brought this new chaos upon themselves by going public. They really shouldn’t have done it yet.
