Imagine a remote stretch of highway frequented by automated 18-wheelers. All that's required to bring the truck to a screeching halt is a bedsheet and some decent timing, at which point the vehicle has no way to prevent a robbery. The truck could put in a remote distress call, but it will still be some time before a human can get there. It's a new era for railroad heists!
We're no closer to solving this problem than in 2007; everybody is still trying to manage the long tail of merely safe driving. Handling humans in adversarial situations like the above is still completely off the map.
