Already a bit late
How do you think Michael Hastings was murdered? Hint: Start with the source code for all of the car's electronic systems, including the brakes, accelerators, GPS controls, wireless network, and of course the airbags, windows, and door locks. Make the evidence go away? Just run the hack from volatile memory so it disappears as soon as the power is lost. Chain of command to trace? Sorry, it was just an independent contractor operating on his own initiative. No orders given, none received, no reports filed. Just a wink and a nudge, and probably a bonus for unspecified special services on behalf of "national security". Nothing to see here.
Remember, he was not drunk or chemically impaired. He was a cautious driver. And his leg was fractured from stomping on the brake pedal very hard. Obviously to no effect. Can't you just wait for the self-driving cars?
Me? No thanks.
