I guess its all about minimizing the damage to self, insurance covers the bike (its an inanimate object after all).
I guess its down to individual riding styles, I expect that when road riding everybody is out to kill me so I tend to give greater distances , signal for longer, and generally try to anticipate what differant vehicles are going to do (Dont worry I am a crap road rider and not very confident in heavy traffic/filtering type skills).
I make the assumption that that anything van/lorry/taxi/service vehicle is going to do any number of random manouvres at any second and will take great delight in adding me to a "notch" in his belt.
Anything driven by a woman with kids onboard is going to be given a very wide berth, in short no 4 wheeled or more device ever takes their actions into account (its a selfish thing , I want to go here now !), until motorcycle awarness is a mandatory part of the driving test nothing will change.
As far as minimizing injury goes thats just a lottery, it would be really easy to say relax dont be tense , slide rather than grip n flip but we all know that unless on the track there are just too many obstacles (moving & unmoving) in the way to permit this.
