Hey Mate
Sorry to hear about the accident. I suggest if you have full comp to go ahead and make a claim. I used to work as a claims officer at an insurance company and the easiest way for you to get your claim through is to put your claim in and pay the excess. Its a pretty straight forward claim in terms of whos at fault so when you make your claim and everything is sorted you will get your excess payment back to you. The quicker you make a claim the quicker you can have your car assessed. What people generally dont understand is that you cannot force another person to make a claim. If this person doesnt want to make a claim on their insurance he or she doesnt have to, not even the police can force that person, at best he or she might get charged wif some sort of driving offence. Hence why we have insurance so they can sort all that stuff for you, thats why we pay them money for... make them work for their money. Basically your car will get repaired or you get a payout and your insurance company will just bill the other party with a lump sum
hope that helps
