On V2V / V2X Wireless Communications > The major concern here is a protocol compatibility and efficiency of communication since the decision should happen in milliseconds and there is no time for extra computation related to differences in a communication “language”. And again, security is NOT ON THE LIST. How destructive do you think it would be if I were to multiply my velocity vector by -1 while traveling on the freeway? In fact, Ctrl+F Security. NOT IN THE ARTICLE!! Holy crap people.

Being that cars operate in physical reality, my guess is the machine would ignore your obviously incorrect spike of data and rely instead on its LIDAR and cameras. Frankly, I see V2X as basically useless outside of coordinating complex maneuvers (high speed, high efficiency car trains on freeways or stopless intersections). But why even have it if the sensors are already aware of what's going on to a reasonable degree of 1-2 seconds of future reality?

  When you have mutliple vehicles, each potentially with their own variant of control software, then each could be internally deterministic but "foreign" to the other vehicle. Kind of like a double pendulum. Edit: But also like that cool double/triple pendulum thing (https://www.youtube.com/watch?v=cyN-CRNrb3E https://www.youtube.com/watch?v=cyN-CRNrb3E) you don't necessarily have to be able to predict the future if you are simply monitoring the present state at a high enough sampling rate. Note that this thing is sampling at 1ms. Not sure what kind of sampling would be necessary for cars, certainly a function of velocity and braking power.

Yeah. No one thinks of security. Remember how responsive jeeps was to the jeep hacks. And then we will send updates via USB drives in the mail. What happens when someone hacks our automated cars and just tells them to keep accelerating. Think of the devastation. You really think any manufacturers are giving much concern to security you are sorely mistaken. They will give us a warm fuzzy that they are, but everywhere I have worked development and new features have trumped security. The NSA will find back doors as usual and will keep them secret to exploit while others will find them and exploit them. Target and home depot can't keep your credit cards safe, what on earth makes you think Volvo or Tesla or Ford will keep you safe Also what about all the displaced jobs. Mechanics, insurance agents, drivers, after market parts, junk yards, and others. Best argument I hear is they will have opportunities for the new jobs automated cars will provide. But no one can say what those opportunities are. Just remember your perfect automated car is only as smart as the imperfect programmer who programmed it. I am cynical about the inability to own a car the loss of freedom, the near constant tracking of my movements by corporations who will sell your soul for money, the targeted advertising and all the other crap. That being said I think the technology itself is awesome.
