  • No explicit source, but it’s common sense and within their abilities, keep in mind recently changed rules around searching in general have changed recently…

    Border agent: I’m going to search your phone give me the password.

    (eventually you agree because it’s a burner)

    You: Here you go

    Border agent: There’s nothing on this phone, no email, no pictures, nothing? What are you trying to hide?

    You: Well it’s a new phone I just got

    Border agent: And you haven’t logged into anything yet?

    You: Ya.

    Border agent: looks like you’re trying to hide something, this isn’t normal behaviour

    You: start looking nervous as the border agent’s tone changes

    Border agent: You’re looking a little nervous now, are you hiding something?

    You: no, just trying to travel

    Border agent: Goes away and talks to someone, then comes back and says, sorry were going to deny you.

    They can deny anyone for any reason. It would ultimately come down to how you handle the situation, but DO expect to be grilled about it if you haven’t set it up to look real.


  • They may have used the proper glue… that foot pedal recall, proper glue, but the workers had trouble installing it so they added soap to the pedal without properly vetting it and that fucked up the glue.

    Something like that could have happened again

    Edit: Just thinking of a made up stupid reason like the soap and thought it was funny…

    E.g: We were supposed to use a size 3 glue applicator as per the asssembly spec, but it was causing some excess glue to come out along the edges as we placed the trim down and it was a lot of effort to properly wipe up on each vehicle, so we started using a size 2 applicator with less glue! 🤦




  • AEB braking was originally designed to not prevent a crash, but to slow the car when a unavoidable crash was detected.

    It’s since gotten better and can also prevent crashes now, but slowing the speed of the crash was the original important piece. It’s a lot easier to predict an unavoidable crash, than to detect a potential crash and stop in time.

    Insurance companies offer a discount for having any type of AEB as even just slowing will reduce damages and their cost out of pocket.

    Not all AEB systems are created equal though.

    Maybe disengaging AP if an unavoidable crash is detected triggers the AEB system? Like maybe for AEB to take over which should always be running, AP has to be off?



  • I think the older Tesla system (HW3) was around 300w, but I think the newer system is more now as they beefed up the compute, but I haven’t seen a number on that. The old system is pretty much maxed out though with no room to grow other then making things more efficient vs just more raw power usage.

    A lot of the older hardware back then wasn’t purpose built for driving and was more repurposed general graphical compute, so it was less efficient hence the 2Kw you were seeing. Tesla built ASICs for the driving computer to bring costs and power usage down.

    With the newer purpose built Nvidia stuff I’m sure that has brought the power draw down a lot though, likely relatively close (better or worse I don’t know) than Tesla’s watt per performance.

    edit: clarity






  • That’s not really true.

    He use lidar in SpaceX because he knows it’s the right tool for their specific job.

    His stance is it’s not that cameras are better, but that cameras have to be so good for a truly AV that putting effort into both means you’re not going to make your cameras good enough to do it and rely on lidar instead. That and cost.

    If the car can’t process and understand the world via cameras, it’s doomed to fail at a mass scale anyway.

    It might be a wrong stance, but it’s not that lidar is flawed.

    Tesla even uses lidar to ground truth their cameras

    Edit: just adding a late example - Waymo, Cruise, and probably everyone out there still use humans to tell the car what to do if it gets stuck. I even bet Tesla will if they ever launch a robotaxi as they need a way to somehow help the car if it gets stuck. When we see these failures with Waymo and Cruise, it’s less “is something there” and more “I don’t understand this situation”. The understanding comes from vision. Lidar just gives the something is there, but it isn’t solving their problem.
