Things cyclists should know … POV driver who's incapable of cycling

On a slight tangent, does anyone know the source of
"90% of UK cyclists also **drive" **
statistic that seems to be floating around now?
Nice (convenient) if it's true but it sounds like spun data to me

In addition to the BC membership, I think CTC quote 94% of their membership have a driving licence. Of course what proportion of cyclists who don't belong to an organisation which records such information have a licence is very open to speculation.
