Grandiose free transportation

no one sane anyway! But the drillers are getting close to the Mohovoric
discontinuity, something like 5 miles deep so its not beyond reason
to think a tunnel could be made, like XanthosNZ says, would be a
chord shaped curve ...[text shortened]... ation which may be true now but maybe more
efficient diggers will be invented in the future.

A mine that reaches to 5 miles is completely different from a hundred kilometre long tunnel at 5 miles down. One is currently around, the other practically impossible.

The operative word there being "practically".
One centruries' impossibility may become the next centuries' toy.
Which of course is no solution to the problem at hand, just a
reminder that a lot of things come off the impossible plate
in time, although in this case, one hundred years from now they
may in fact solve the problem of doing just that but have evolved
transportation wise past the need for doing so. For instance,
Mr Fusion of Back to the Future fame or some kind of 'anti-gravity'
device, something I envision more as a field acceleration device
where every atom is accelerated at the same time as opposed to now
with rockets, its more of a sound/pressure wave coming up from
the rocket and finding its way upwards which increases the velocity
with gradients. Pure speculation of course but thats what science is
all about. You have to speculate first to get something real to work.
And there are hints of just such a device, you know the one I mean,
where the spinning superconductor above a magnetic field is
proported to be reducing gravity, which in space would be the same
thing as a reactionless drive. Which also of course will need much
verification before anyone actually believes such a device can be made.
