I will make no attempt to defend the specific recommendations I mooted. There is better work, in any case, in the academic domain on fixing our flawed civil-engineering auction processes.
The problems anyone campaigning for auction reform runs into are three-fold. One, it's a boring problem with boring solutions. Two, there are vested interests. And three, Americans suffer from a just-world bias when it comes to infrastructure [1]. The latter is apparent even in this thread. It's difficult to find solutions when people vigorously defend a clearly-flawed system.
