I'm surprised the police haven't been involved - just because this is an ambulance it doesn't excuse dangerous driving. I'd have my insurance company claim every bit of damage possible and frankly I'd have the driver of the ambulance up on a dangerous driving claim with the police. From the sounds of it, the only thing that saved your girlfriend's life was luck.

It annoys me that the emergency services seem to feel the rules don't apply to them. there has recently been a case where a cop has been done for dangerous driving during a training execise where he killed someone. I don't care if they're trying to save someones's life - doesn't excuse taking another!
