I can safely say I won't be doing it again. The motorway was clear, I'd previously pulled over to offer assistance to a stranded motorist in a Ford Focus who had broken down awaiting recovery back to somerset in the hard shoulder, Rita was sounding a bit rough and generally felt 'different', once I was confident that she was okay I decided to follow the normal routine but it isn't worth the worry of wondering if you did get snapped or not!
Ah, well given that it is a CCTV camera if they saw you doing that you might be getting a brown envelope anyway. Stopping to help someone on the motorway is illegal and stupidly dangerous. The Police / Highways / trained recovery drivers are there to help them, you don't need to get involved.
