Hi Scarface mate,
I am really sorry to hear about what happened- as everyone else has said, the most important thing is that you are ok. A car can be replaced, your health/life can't. I'm sorry to hear about the tendon injury- but as you are young that will hopefully heal up quite well in a little while. Don't try and rush back to work or strenuous activities too quickly, you need your recovery time.
As for the incident, I think there are some very valuable lessons to learn. It provides an arguement for increased security measures, such as a tracker system (if nothing else its a deterrent to all but the most devious theives). I also live in London and I always lock my door as soon as I get into the car, before anything else. Maybe it would be an idea to create a thread/section devoted to driver safety/security to minimise the chances of something like this happening to any of us.
I wish you a speedy recovery and hope that the insurance company pays up.
