The problems with getting public infrastructure projects done in time or at all are political, not technical.
There typically are no technical solutions to rhose.
There typically are, but sometimes the technical solution is bad for those in power, or they're unaware of it, or it hasn't been discovered yet.
Kind of - the art of fortune telling plays a big part in things
It's not needed now, but we think that it will be needed in the future
It's needed now, but we don't know if we will use it in the future
How MUCH will it be needed in the future
Will there be a future technology that makes this investment unnecessary, or even obselete before the project ever completes
For the latter, a big argument of "No need to invest in commuter trains" argument was "self driving cars are 'just around the corner' and they will make mass transit a quaint thing of the past" was used to deny investment in trains.
If empirical observation is 'technical', then keen eyes can spot the grifters before they can be elected or corrupt the already-elected. Then we just need the will to permanently deter them.

Not that they can't, but they won't.
