Strict liability is the only answer, not least as it would - I think - make everyone have to have a black box / camera if they want to afford insurance.
AFAIK this is already starting to come in, at the mo only for those wanting to save a bit on their insurance by having a camera running all the time, but I can see in the years to come them being more popular.
Yesterday I caught on camera a 4x4 ripping its front bumper off on my properly parked car, well, got a few still images, but anyway it instantly sorts the 'it was already like that, word vs word, who dunnit' questions, I was 3 floors up so not able to actually stop it from happening.
