I always turn it off. We have the Truma crash sensor, but why trust technology when it takes 8 seconds to turn it off. And as Channa said, the pigtails are highly pressurised.
Is it likely to be an issue? No, probability is very small. If it were to happen would the impact be severe? Yes, potentially.
When I used to to risk management stuff I'd then ask 'how much does it cost to eliminate the risk?' As mentioned, 8 seconds of my time per journey....
But, hey, that's just my view
