I think you already know the answer. Do the right thing... as you say, if you hit a little kid running out into the road after a football, and the insurance gives you (and the child and family) a big f*ck you, how will you live with yourself?

Think about the possibility of a 40' square room 20 hours a day and a boyfriend called Bubba... that alone should be enough to put you off!
