  • The problem is computer vision has a LONG way to go before it’s truly on par with human eyesight. Musk loves to crow how cameras are sufficient since we use our eyes to drive.

    The thing is, eyes have special neural circuits that detect motion. They essentially filter out unnecessary information and send just the motion details to the brain. This prevents the brain from being overloaded with every detail the eye constantly sees.

    And being overloaded with everything is exactly what computer vision currently does. It’s just a stream of images that the computer must analyze completely. So it’s working exactly opposite to how the eye & brain works.


  • I recall when I bought my first hybrid that the dealer said there were something like 15 different computers controlling things, from the ICE engine to the transmission to the charging of the battery, etc. They weren’t networked together.

    I also once ran afoul of a software bug in the ECU of a Honda CR/V. That’s the embedded system that manages the whole operation of the engine - from fuel injection to timing to emissions etc. As they progress through model years they use different ECUs that require different software. Even though I work in IT, I wouldn’t feel comfortable trying to update it myself, given the different models, firmware revisions, etc. I was more than happy to take that car to a dealer to have them confirm my car had buggy software and to upgrade it to the right new version.
















  • Hell, I’d be happy with the manufacturers ensuring buggy ECU software is kept properly up-to-date. Long story short I spent months dealing with dying batteries in a pre-owned Honda CR/V that I bought from a dealer. After multiple dealer visits, jumpstarts from AAA, etc. I finally found references to two recall notices on my own that described my symptoms perfectly. The only problem was that my cars VIN wasn’t in the list of those affected by the recalls.

    I took printouts of the recall notices to the dealer, and they agreed it sounded like issue I was having. They updated the ECU software and I never had battery issues any more as long as I had that car.
