Yes I crashed and it is partly my fault and panic can get the most of you. Short story is, im over taking someone guy comes flying up fullbeams me. I pull in once I have overtaken he pulls right in front of me. I give him a little flash as I aint happy, nothing major just a quick flick. He puts his fogs on then slams his brakes on. I lock up hit his bumper then do a 360 or 720 down the motorway at 70 and come to a stop. By now hes out of sight. I check the car over and the bumper is knocked back and my side lights smashed. I make my way down the motorway and finally see this Golf half pulled over with hazards on. I get out make a phone call and walk over to the car. It then started driving away. Finally the opened the window and said they phoned the police, ok fair enough I just waited till they came. They did, took my story and breathalised me. Passed it as my last drink was prob a month ago. They said they were not going to do me for anything. I asked if I should get some photo's and they said that would be ok, and if they did try to claim for anything more than the busted bumper they would say there was no other damage. I only got a pic of my car as they drove off while I was taking the pic. Started walking back to my car, it was dark and I nearly knocked my self out by smashing my head on a road sign. The officer also told me a fatal accident had happened not to long ago on the same road where I driver spun his car off the road into the ditch. I am a little shaken up and trying to take the pic off my phone onto my pc took a little while. A lesson learned.
