I read apparently that Southern had been having problems with its train

GPS is only there to cope with short platforms and to tell the train *which*
doors to open. For example, when stopping an eight-car train at a
seven-car-length platform the software will lock out the rearmost doors, to
prevent passengers from hurling themselves onto the track. ...


Which begs the question:
Is it accurate enough to know if the driver mischievously or
carelessly stops with the _rear_ 7 cars in the platform?!
