We know ecclectic mesh IOT is coming. We know that. But it seems to me that autonomous cars must have a secure network to be safe. Id love to see SAFE in there cars with LiFi and soft radio mesh. Some of the glass roof cars will recharge while out in the sun, now that is not primary but such a great back up.
Tesla has said they will do low Earth orbit satilites but that is fine as an additional layer but should not be centra as space is subject to disruption in that band. That LEO net could connect the cars transoceanic.
While I am on Tesla cars let me note an infuriating article that tried to say gas cars would be better autonomous vehicles without citing it. No, no they wouldn’t. Teslas at least will have a radically lower cost of operation and much higher reliability and up time. Radically less for energy and nothing for maintenance and down time and much better performance. Gas cars would suck.
