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. Apparently it's
necessary in these litigious days when anyone stupid enough to attempt to
alight from a door that is not at a platform will try to sue the TOC,
rather
than accept personal responsibility for doing something so dumb in the
first
place.

What if it was dark? Some platforms are very poorly lit. Seems like a good
idea to me.
