ive got a good one for you.....

a lot of MoT places seem to be more rigidly enforcing rules onprescribed areas of visibility to the extent of failing cars for having a magic tree hanging off the rearview mirror.

now obviously the rearview mirror is excluded as a failure point for obscuring visibility.

So what would happen if you removed the mirror on say a semi track car with carbon rear window and in its place put a go pro camera or similar??

Logic would dictate that visbility is no worse impaired so it is no more unsafe than if a rear view mirror was in the same place.

However, would the fact it is a camera, NOT a mirror mean it has no exception to the visibility rule and thus be a point of failure???

a practical example. I have a camera in front of my mirror for trackday use and insurance purposes. it is deliberately located to not obscure driver visibility of the road and is entirely behind the mirror when sat looking from the drivers seat. Perfectly legal under current MoT rules. If i fitted carbon rear windows to save weight (i cant see much out back due to spoiler anyway so no visibility loss in practical sense) and removed the redundant mirror, would the camera now be a fail point??
