Why Can't People Put Wheel Trims On Right?

Driving down the road at a law obiding speed, nothing out of the unusuall. No car infront of me 1 car behind and a Fiat Brava coming in the opposite direction with its wheel trims wobbling becuase they are not on correctly.

A few seconds later I hear a crunch and I see the 2 drivers side wheel trims come off at the same time. The rims are coming straight for me and the metal ring inside the rims come away and come straight for me too. There was little I could do. I couldnt swerve right because that Brava was coming, I couldnt slam on as there was a car behind me. All I could do was brake and slow down. I did and the 2 trims just missed me, but the 2 metal rings where still coming for me. One got caught under my car, but the other one rolled right over. :mad:

I now have 4 really big chuncks missing from my paint on the light panel. I am not talking little scratches I am talking knocked the paint off all the way down to the plastic. The whole panel will have to resprayed becuase people dont check that their wheel trims are on properly. :mad:

I have tried to paint the holes. They are red now instread of white but you can tell that they are there as there is a pit about a millimetre or so deep.
