  • I completely agree that if there are tools that can allow a vehicle to “see” better than a human it’s absurd not to implement them. Even if musk could make a car exactly as good as a human, that’s a low bar. It isn’t good enough.

    As for humans: if you are operating a vehicle such that you could not avoid killing an unexpected person on the road, you are not safely operating the vehicle. In this case, it’s known as “over driving your headlights”, you are driving at a speed that precludes you from reacting appropriately by the time you can perceive an issue.

    Imagine if it wasn’t a deer but a chunk of concrete that would kill you if struck at speed. Perhaps a bolder on a mountain pass. A vehicle that has broken down.

    Does Musk’s system operate safely? No. The fact that it was a deer is completely irrelevant.








  • I don’t think it’s “just” LoRa on 2.4ghz, because if it were existing lora devices wouldn’t be able to decode the signals off the shelf, as the article claims. From the perspective of the receiver, the messages must “appear” to be in a LoRa band, right?

    How do you make a device who’s hardware operates in one frequency band emulate messages in a different band? I think that’s the nature of this research.

    And like, we already know how to do that in the general sense. For all intents and purposes, that’s what AM radio does. Just hacking a specific peice of consumer hardware to do it entirely software side becomes the research paper.
