So why doesn't Congress just get off its butt and just mandate man-rated software (that cannot be hacked), mil spec GPS systems (that cannot be stolen for nefarious purposes), and non-hackable networks that tie it all together? If you're going to add this kind of information to mapping systems, all the components better be dead-on accurate. My GPS is accurate to 10 meters - that's 2 lanes on the highway. To me, that's not good enough.
As an aside, how does PTC know which track a train is on, say, in the NorthEast Corridor? If there's onboard hardware involved, how does anyone ensure it's secure?
