that might be the case. I bumped into someone about 3 months ago, T-boned the women, I basically drove over the stop street at the blind corner into her, looked like my fault but my statement was still contradicting to hers, the total costs of my damage about R5000, it was a light bump , fixed most of it myself, now having insurance companies over your ass all the time saying you have to pay and its your fault, basically, case 1 : they come to you saying you have to pay. I tell them to read the statement, next case : they do the same thing saying that they have read the statement, so I ask them to prove it, it takes even longer and more money for them, they will come back with a law suit most probably , keep in mind I have no insurance. So ok, her costs is about 20k as mentioned , I still refuse to pay, this time I ask them to prove it and tell the same thing to their lawyers. their lawyers agree, its back to square one for the companies, If their lawyers don't agree I ask them what procedure they followed. at the end of the day its not worth it for the companies to sue me. Now saying a rear bumper is my fault is not the case, acording to the K53 driving instructions you have to look in your rear mirror before you make a stop, if its a emergency stop then you need to tell them what the emergency stop is for, and in this case it will not be my fault due to my slow reaction but rather the person/ truck in front of you. If you did look in your mirror you would have seen me. If they didn't then I can put in a counter claim. ok it can be my fault yes but you still have to prove it. Meaning the insurance company has a big job proving my statement wrong.
so the rule of the thumb is: If you have a accident make sure you do not admit it is your fault unless you want to screw yourself.
