    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.

      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.

      Why are you misquoting the article that is not what it says

      The real quote

      LiDAR is essentially radar that uses light instead of radio waves…

        Why are you misquoting the article that is not what it says

        Why are you accusing me of something I didn’t do?

        From the bottom of the article:

        Updated to correct an error in describing how radar works.

        I quoted it correctly at the time. They just edited it after I commented.

    Literally every single day we have idiots doing Musk’s PR work for free.

    Downvote Musk spam. The billionaire doesn’t need your help ensuring his businesses stay in the 24 hour news cycle.

      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.

      If this was a puff piece, I honestly wouldn’t have bothered posting it.

        Most people on the entire planet are aware of how shitty he is at this point. Everyone that would not purchase a product related to him is already not buying said product. There’s no more people to convince. Don’t act like a white knight while degrading the content in this community.

        I swear this specific community is turning more people off to lemmy than any other. These type of posts are why.

          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.

        He’s right though. We can’t go a day without some inane bullshit about musk getting posted. This event happened 8 years ago, it’s not even news. It should have “2015” in the title. This is a bad post, and I’m disappointed we always have to have these kinds of posts around.

      Sunk cost. The price for these “premium” cars is sillyz and the features don’t work. But people wouldn’t pay such a price for unfinished crap, right? Right?! So they justify it to themselves and get defensive.

        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.

          We are trained to this. For decades we both consume ‘brands’ and are ourselves ‘branded’.

    As 2023 FSD frequently attempts potentially lethal actions, 2015 FSD must have been spectacularly awful. The headline neglects the fact this was 8 years ago.

      Shhhh, we’re busy jerking off to today’s Musk hate article. The ritual must not be interrupted, even if we have to dig out old news.
