Driving late last night along a busy side road that runs parallel to a main road, the side road joins the main road at an angle. As I approach this junctions there's already a small Citroen car at the Tee junction waiting to move on to the main road. I pull up behind it and stop with a good metre or more distance, the main road isn't busy at all but the driver in front doesn't move onto main road. So just as I'm wondering if he has broken down or something, the driver very slowly gets out his car. I can see that he's a very elderly chap. He gets out very gingerly, puts one hand on his hip and awkwardly starts walking towards my drivers window. I'm still thinking this poor old man, whose possibly in his late 60's, perhaps early 70's has broken down, so I wind the window down. Just as walks past the back of his car, he stops and has a good look at his bumper. So I think OK, maybe his exhaust has fallen off, so I greet him :- Speedy: "You Ok Sir ?!" Elderly Driver: "You've just hit me !! Why did you hit me ?" Speedy: <Totally shocked, thinking I'd misheard him > "Sorry ? Say again !" Elderly Driver: "You've just hit the back of my car !" Speedy: "I say no I haven't I'm a good metre or two behind you." Elderly Driver: "That's because my car has been shunted forward it was quite a whack !" Speedy: "Are you on drugs or something ! You were already stopped at the junction, I pulled up slowly behind you and leave this massive gap." Elderly Driver: "Look young man you made a mistake and went into the back of, don't try and deny it. I think those people over there in the bus stop must have seen it!" He actually starts walking towards the bus stop that is on the main road and the two people there start to move towards him. Just then I remember I have dashcam installed in the Accord. Speedy: "Hold on a second, you want some evidence, let me show you some evidence ! I have a camera installed in my car, this has recorded everything that has happened so far and is recording everything that you are saying. There's no way that I hit your car or even came remotely close to hitting it!". Elderly Driver: "Well I'm sure I thought I felt something !" Speedy: "No you didn't ! You're simply trying to pull a scam on me. If you don't get back in your car and get the hell out of here I'm calling the police !" Elderly Driver: "I'm not scamming you honest it was a genuine mistake !" He says this, quickly turns and hurries back into his car(no more limping) , starts it up and goes right, despite having been stopped on the left side of the junction originally. I look across in that direction and then realise that people at the bus stop have also disappeared somewhere (no bus had come in that time). Quite dazed at what just happened I sit there for short while longer before heading off home. I get home, whip the SD card out of the camera, hoping to go over the recording only to find that the camera had stopped recording over a month ago. Initially I was quite angry and disappointed at not having the footage then it dawned on me that just having the camera there had just saved me from having been conned into being blamed for rear end shunt that never actually happened !
