What's Wrong Here?

Hint: Are these conduits properly installed?
Randy Dettloff, a superintendent with JLT Electric Construction in Schaumburg, Ill., found this installation in a parking lot near the company’s offices. Section 410.15(B) in the 2005 NEC permits metal or nonmetallic poles to be used to support luminaries (lighting fixtures) and as a raceway to enclose supply conductors, provided six conditions are met. But there’s no chance that any of the six conditions of this rule have been met here.
Most of the older types of underground wiring methods, sometimes called "parkway cable," have lived a long life, only to disintegrate because of corrosion. I see this all over the country. This is just another situation where physical damage caused by vehicles and/or vandals can lead to potential electrocution hazards.
