Yes of course it does. Victims of a train crash suddenly become experts on the design of railway signalling systems, Jenny Tong got the wiring regulations changed after her daughter was electrocuted by drilling into a power cable. Just wait until an MP has a relative die in a cycle crash and see how many MPs are willing to vote against their friend's call for compulsory helmets.
I had been thinking about Jenny Tonge. In that case (her daughter's death), the kitchen fitters had buried an unprotected cable in the wall, not deep enough, running at an angle from the fuseboard to the cooker hood. Almost everything about that was contrary to wiring regulations and established good practice. Anyway, Tonge was inspired to promote Part 'P', which is expensive and highly bureaucratic. I don't know how many lives it has saved, but it hasn't stopped cowboys doing electrical work - both outside and within Part 'P'.
So I suppose Part 'P' is to electrical safety what the cycle helmet is to cycling safety: i.e. over-rated and often counterproductive. Even so, Tonge's experiences have a more direct link to her promotion of electrical regulation than, for example, the sleepwalker who fell off the balcony, who campaigns for mandatory cycle helmets.
