On the whole I’m all for this one, but as andrewm points out it would have to be well thought out legal wise. With ref to safety cards during my time as a Traffic Officer/Dispatcher I always asked the crews concerned before obtaining them and they were always very ok about handing one over, not that I have many. I would like to think that we could trust each other in our trading/selling etc but some kind of back up would I be smart I guess.
