    Theorizing and thinking out loud:

    More and better cameras and sensors are good, but why be limited to just your own car's sensors?
    Cars should share camera and sensor data with each other, effectively allowing cars to see through walls and around corners. Even parked cars can contribute to the collective, keeping track of things and broadcasting data.

    Some random thoughts:
    1. Maybe it doesn't have to be raw sensor data, but objects, size, position, vector, etc that gets broadcast
    2. Latency could be a problem - Tesla servers would have to collect the data, figure out which other cars are nearby, and send to just those cars. If this takes too long it may not be useful.
    3. Processing becomes much more complex - software, processing speed, decision making and reaction time may be affected

    Good idea? Feasible?

    Yep. The industry has been very into the concept for years, longer than autonomous vehicles have been worked on seriously.

    A system of fully autonomous networked cars wouldn't have parked cars in the sense people are used to them now. No parking on streets at least.

    What's learned by one car is known by all cars. Cars know the position of all vehicles nearby without even sensors because they all report GPS coordinates and connect.

    The first goal was exactly that seeing around corners and through obstacles idea. There was a DOT sponsored system in Ann Arbor working on that sort of basic early warning connectivity a few years ago. There would be value in just warning traffic behind you that can't see that you're braking rapidly.

    This revolution will overlap with autonomy.

    One implication I think is that there will be more pressure sooner than one would otherwise expect to outlaw human drivers in urban areas. There would be a big leap in functionality and safety going from a few human drivers in the mix to 100% autonomous and networked.

    Anonymous driving by sharing everything? Where is one to hide with all those cameras? Is nothing private anymore?
    oh - you said Autonomous . never mind.
