MISRA  

 Hi Gavin, welcome the the wonderful world of Wikipedia. 

 I take your point about the group wanting to move away from the Motor Industry association, however, articles are intended to be informative and not written from the point of view of how an organization would like to present itself. 

 MISRA is provided as a link whose article spells out the acronym; so lets leave it as-is.  Perhaps a history subsection would be appropriate where the change of emphasis from purely Motor industry orientation to a more general scope was outlined?
