Too slow:
This was done to lessen AMG's legal responsibility when these wheels were repaired. If you to do away with the wheel nuts while the tire is full of air the wheel assemblage could blow up. By controlling who was capable to purchase the socket AMG could insure that only trained technicians could service the wheels. It turned out that many owners were capable to obtain or make their own sockets and purchase regular hex flange nuts from the many Army surplus dealers. The most recent two piece wheels which are standard on the 2000 models now come with hex nuts.

Underground electrical utility vaults and streetlighting hand holes have the same 5 sided configuration to keep the public from gaining access. I dealt with those for years. Still have some sockets that fit them.

As do the main valve and access caps on fire hydrants.

Over here where there is a domestic gas meter outside of the property there is a three sided key to fit.

If they were really clever they would have also made it left hand thread.

My Father always said the lightbulbs at Grand Central Station in NYC threaded backwards to prevent theft. I was never sure if it was an urban myth or not.

  The engine ECU in a 5.0 litre Range Rover is covered by a metal bracket held on  by a 5 lobe tamper proof Torx style bolt. The question is? Who gives a monkey's you know what. . Aaaagh!

The Boris-Bikes in London have an odd tyre size. So if you pinch one you can't get a tyre replaced!

I suppose you just steal another whole bike then!
