That wasn't my question. Any deficiencies in the design of the installation are irrelevant to the matter of your competency.
I'm more interested in establishing the deficiencies in the design of the installation than convincing other people of my competency to do so. I would hope you would judge my competency by making your own assessment of the evidence and comparing our conclusions. I know plenty of "qualified highways engineers" who are not competent.
Furthermore, your assertion that they are only appropriate for "long shallow curves" appears to be made up.
I made no such assertion.
