    LiDAR is essentially radar that uses light instead of sound

    Radar doesn’t use sound. It sounds like the author doesn’t know the difference between sonar and radar.

          A lot of articles that either use that buzzword or are published by sites that have that in their name are utter garbage. i.e rediculous predictions, inaccurate headlines/content etc.

      Yeah, it uses radio frequencies. RaDAR stands for “Radio Detection And Ranging”. It uses radio waves (usually in the microwave bandwidth) to detect things. Basically, since those radio waves are affected by the Doppler effect, you can have a computer do some math to determine the speed of whatever those waves reflected off of. Because the Doppler effect changes a wave based on how fast an object is moving relative to an observer. So if you’re a stationary observer, you can figure out how fast an object is moving relative to yourself, purely based on how much that moving object changes the waves you’re reflecting off of it.

    “We’re trying to have those conversations with Elon to establish what the sensors would need to do,” Baglino added. “And they were really difficult conversations, because he kept coming back to the fact that people have just two eyes and they can drive the car.”

    Yes, and people crash cars all the time Elon…

    If you want an autopilot with the failure rate of a human, then you might only need two eyes. If you want an autopilot with a near zero failure rate, you need much better telemetry data

      Our heads are just loaded with sensory capabilities that are more than just the two eyes. Our proprioception, balance, and mental mapping allows us to move our heads around and take in visual data from almost any direction at a glance, and then internally model that three dimensional space as the universe around us. Meanwhile, our ears can process direction finding for sounds and synthesize that information with our visual processing.

      Meanwhile, the tactile feedback of the steering wheel, vibration of the actual car (felt by the body and heard by the ears), give us plenty of sensory information for understanding our speed, acceleration, and the mechanical condition of the car. The squeal of tires, the screech of brakes, and the indicators on our dash are all part of the information we use to understand how we’re driving.

      Much of it is trained through experience. But the fact is, I can tell when I have a flat tire or when I’m hydroplaning even if I can’t see the tires. I can feel inclines or declines that affect my speed or lateral movement even when there aren’t easy visual indicators, like at night.

        To be fair, 98% of drivers seem to barely be able to hold a straight line and can’t see past the end of their hood, let alone do shoulder checks and be able to hear anything over the stereo turned up to 11. So I’d take my chances with the half-baked autopilot that can at least discern what a red light looks like.

        I followed one gentleman for about 10 blocks before he stopped and I could tell him that he was missing the entire tire on the rear left of his car. There were a lot of sparks and metal screeching. Not a clue.

        Just adding to your point, when F1 drivers were asked to play a racing sim, they could not perform like real life because they said no matter how good the sim is, it doesn’t provide the feedback of a real car.

      And people turn their heads, move their eyes across their windshield, change focus to look ahead or closer, look in their mirrors, listen for sounds (emergency vehicles, car honks, etc), are able to do things like look through gaps and other car windows to adjust to partial obstructions.

      The fact that he doesn’t realize you need a multitude of sensors to do even a little bit of what a human can do tells you all you need to know about Elon’s so called brilliance.

        Even the social aspect of driving eludes him. You and another driver come up to a 4 way stop at the same time, crossing paths. They wave you on to be polite. You wave back and go first. How and when does he plan to handle that behavior?

      Anybody else remember the now-removed Tesla blog post from 2016 arguing that FSD will require LIDAR? Idk why they’ (Elon) are so stubborn about it. It can see through fog and darkness . Add that data to their model and they would probably already be near deployment readiness of real FSD.

        Automotive lidar costs around $500-1000 to add to a car.

      Well we perform pretty well with just two eyes, but the difference is that we are a highly skilled general pattern recognition machine that you just can’t recreate in software yet. A few lines diverging with a bigger and smaller circle under it? Guess that’s a truck going that way. Oh the lines are changing angles? Holy shit the truck is coming into this lane!!

      A person approaching on foot or a bicycle from my right side at the coincidentally perfect speed can accidentally stay within both my human eyes’ blind spots (behind the support pillar) as I come to a stop at a 4-way. I have learned I need to crane around a bit before proceeding, or their frightened and angry face will suddenly lurch into view too close for comfort. The robot must be designed to have zero blind spots because humans are ridiculously good at hiding in them. Especially the little humans.

      Counter point: If I didn’t hear how badly he runs his businesses, or how bad his company’s products are. I would have easily bought one or more of his products.

      I have backed out of Tesla pre-orders because of the bad publicity, many reports of bad build quality, and terrible business decisions.

          Last time I mentioned Musk in a casual conversation, this one guy kept going on and on about how he thinks he’s a genius and how Twitter will be so much better now and how he’ll bring us all into space and how people only don’t like him because he’s conservative. He would have kept talking forever if we didn’t change the subject.

          My point is that lots of people don’t know how shitty he is. Some people live in an echo chamber where they don’t ever hear about that stuff because certain people want to sell a narrative where the rich man is competent and the poor people are just jealous. Others just aren’t very attentive.

          Not everyone is you. It’s good that you know he’s shit, but you shouldn’t assume that everyone knows everything you do. It’s important that we dispel the myth that the rich and powerful got that way by being smarter than us. If it takes a hundred articles to do that, then it will all be worth it.

        Also a lot of people will treat any shitty-shit consumer piece of crap as being part of their “personal identity” (an effect very purposefully created and used in the marketing strategy of lots of brands) and that is much more so for something which is way more expensive than pretty much all consumer gadgets out there and which people most definitelly are seen with (in some ways its almost a cross between a 2nd skin and a home away from home).

        As soon as people treat something as part of their identity, any criticism of it is felt as a criticism of they themselves, which depending on the social environment and maturity of the individual, can be taken as an attack.

    You know who also didn’t listen to their engineers? NASA back in the day with Space Shuttle Challenger. You’d think Musk would be cognizant of the importance of listening to engineers when they bring up safety concerns, particularly as he owns SpaceX.
