It comes up in virtually every article about automated cars, with zero explanation. If it really is just that journalists are too afraid to ask / don't know better, that's pretty damning for the entire tech journalist industry!

Sure, they can operate without 5G, but I can see strong benefits to having connectivity. Traffic, construction, road changes happen and fully automated needs to know where it’s going. It seems like a must to me, and definitely assumed for any future car platforms.

  I'm not saying they don't need the internet, just that 5G is specifically for super high speed internet. Why can't 4G do all that? Or your home wifi connection at night?

  First, all of that can be done with 4g. Second, supposing you did need connectivity to have a self driving car, the challenge is having a good signal everywhere, not having 5g. You can't even get 4g everywhere. Third I would never purchase a self driving car that requires any connectivity in order to work well.

It comes up in virtually every article about automated cars, with zero explanation. I've noticed that. If you were just doing car to car communication for automatic driving and didn't need to send ads, track, or remotely update the car, the way to do it would be through the vehicle radars. That's how aircraft send altitude, ID, and anti-collision data back to the ground and to each other. Since you know the range and direction of the signal source, totally bogus signals are readily detected. Doesn't even need a permanent ID; choose a big random number at each start. But no. The anal probe approach is essential to so many business models.

    That's the whole point. You only need info about things you can run into.

Likely due to an intentional misdirection campaign by the carriers poisoning the mindspace of journalists: https://pxlnv.com/linklog/5g-pixie-dust/ https://pxlnv.com/linklog/5g-pixie-dust/
