Indeed. Here's a simpler one than the "sekrit tech elite" wanting to kill you...
What happens when the equivalent of the Mariposa botnet, but this time for autonomous cars, roots 12 million of autonomous cars?
But, this time, we have to believe that security is going to be done correctly, right? (this time, promised, no backdoors, no 0-days, no compromised servers, no compromised keys, etc.)
I does really hope this technology rolls out as slowly as possible because the security issues do really scare me.
