>you make an assertion and you back it up with facts.

Over the past year, OPB has done just this in several threads right here on this forum.

>So tell me...what exactly is wrong with the system?

There are at least three systems which aren't interoperable with each other. What will really sink PTC is the dismal return on cost of investment, precisely what did in cab signals in the 1930s. Cab signals are essentially a primitive type of PTC, and all cab signals from that era, US&S and GRS, are -and still are- interoperable (except, of course, in territories like the NEC where it's been replaced).
