Wow this one's gone right off topic chaps! ;o)
This safety check stated they recorded 16 vehicles as unsafe.
Ok that is a black & white issue.
Either there is nothing wrong at all = Safe
Or you might just have a marker light bulb out = Unsafe.
As we 4x4 people have found out to our cost, statistics can say many things depending on who is reading them and what they want to see.
Unless you have the full facts in front of you, i don't see how it can help to get 'up in arms' over these figures.
I'd like to see the actual number and type of faults before making a judgement TBH
