  • even if you CAN rely solely on vision, why hamstring yourself?

    Their stance is that by using lidar OEMs are hamstringing themselves on solving vision because they are so reliant on it. They spend less time and resources perfecting vision so they never truly solve the problem. From their perspective you got it backwards.

    and there’s no good reason… just add extra sensors

    The more sensors you deal with, the more your attention gets divided. You aren’t laser focused on one thing.

    The extra sensors also cost a lot of money, you can’t put waymo’s sensor package onto millions of cars that consumers can buy when the suite is 10s of thousands of dollars (and originally well over 100k).

    By focusing on vision where the system can be put onto millions of cars, you can get massive amounts of extra training data and training data is going to be a huge part of solving this problem.

    You might not like the reasons, or their stance, but it’s not such an unreasonable position to take. Mobile Eye even cancelled their next gen lidar project after seeing improvements in vision and radar. What happens when they keep seeing improvements in vision and now radar isn’t needed?

    I don’t know if you’ve ever used AP but all the crazy headlines you see about it are idiots in cars being idiots. As a L2 vision only system it works very well. If people wanna blame Elon for convincing people to be idiots, sure, you can do that, but that has nothing to do with the actual technological approach they are taking. They’re two different things.

    The point is that to be truly autonomous when vision is the only fail safe reliable sensor, then vision MUST work to have a truly autonomous vehicle.

    You can’t rely on radar without vision or lidar because it can’t see stopped vehicles at high speed. This a deadly serious problem.

    You can’t rely on lidar in rain/fog/snow/dust because the light bounces off of the particles and gives bad data, plus it can’t tell you anything about what the object is or might intend to do, only that it’s there.

    Only vision can do all of those, it’s just a matter of number of cameras, camera quality, and AI processing capabilities.

    If vision can do all those things perfectly, maybe you don’t need those other sensors after all?

    if vision can’t do it, then we won’t have a truly autonomous future.

    The other sensors are a crutch because the vision problem is so hard.



  • The cameras have overlaps which can be used to measure depth and distance.

    There are multiple front cameras

    The side pillar camera has overlap with the side rear facing

    The 2 side rear facing each have overlap with the rear.

    Edit: I imagine their weakest depth/ distance perception with the current set up would be their side pillar cameras. But they could also probably do some calculations with how fast it passes from front to rear.

    Nothing you said there can’t be done by cameras other than sound and the car has a microphone inside. We just might not have the capabilities yet and need to keep improving them.

    All it really means is maybe the car needs more cameras and more microphones.

    Determining distance with images from multiple angles over time can provide accurate distances and velocity







  • The idea of don’t swerve for deer is very common and is taught in driving schools. If you’ve never heard it until today, well you were let down and today you learn. You don’t know dismiss it because you haven’t heard it.

    Swerving is dangerous and even if you think you can do it safely, having a deer appear while travelling at high speeds is risky, even more so at night.

    You’re supposed to slow down but stay in lane.

    The reason you’re supposed to swerve for things like Moose is because moose are big as fuck and tall, and if you hit one head on, you will cut the legs out from under it, and it’s massive body will roll through the windshield and crush you, killing you or causing massive bodily harm.

    This is from the Virginia DMV for example (emphasis mine). Them not having something about moose is actually bad as well.

    Deer/Large Animal Hazards Tens of thousands of crashes with deer, elk, and bears take place in Virginia each year, resulting in fatalities, injuries and costly vehicle damage. To avoid hitting a deer or other large animal:

    • Be alert at dusk and dawn especially in the fall.
    • Slow down if you see a large animal near or crossing the road. Large animals frequently travel in groups; there are likely others nearby.
    • Use the horn to scare the animal away.
    • If a collision with a deer or other animal is unavoidable, do not swerve. Brake firmly, stay in your lane, and come to a controlled stop.


  • There are a lot of scams out there pretending to be Musk. If you want to watch a SpaceX launch, there’s probably at least 1 scam youtube stream out there that looks legit with thousands of viewers and then turns into a scam before the launch.

    After all of the send me crypto and i’ll send double back… I find it hilarious that he’s now telling people to do things and he’ll pay them… and it’ll be even funnier when they realize they don’t get it and were scammed into giving him their info for no money.
