I've been holding off on posting some stuff so I could keep my word and let my next post about drones be 'Fresh Meat'. I got that done, and this post has been burning a hole in my keyboard.
I dunno how deeply you have considered the massive amounts of highly personal information autonomous vehicles will be able to compile on you. I hadn't thought of that as much as I had the ability to cause you to die, in all the various ways vehicles can kill you, by remote control, or just to have your car deliver you to the torture palace for interrogation.
This is why I drive a car without even electronic ignition. Nothing in my car can be hacked without a hacksaw.
I reckon we need to consider some safeguards, and far beyond those measures we take with our computers and phones to secure them from hackers. Since we see how well that has been working (not!), we can see clearly that net connected vehicles are going to require an order of magnitude better security - and not just from ordinary hackers.
If such vehicles aren't secure from state actors, I'll never have one. I trust muggers more than I do cops, TBQH.
