I have the same camera, and one thing I've noticed is that the on-screen GPS speed differs to the speed on the video file - sometimes there can be 5mph more on the video than recorded via the GPS metaData...so I do agree that the camera car could have been on the limit and not speeding as per the initial video.
See attached - the software shows a different speed as to the video...
He should get them checked by a professional because they definitely are not. I also had this guy behind me and was dazzled by the rear view mirror in broad daylight.
Well this is an easy one, right? Go onto your local Police website, report non-injury traffic incident with car details and presto! 6 points for the idiot.
For the record, GPS is not an accurate form of speed measurement - unless you are using military grade equipment - which a dash-cam will not have.
For example, at 11-12 seconds into the video, the GPS is showing 4MPH and the car is almost stationary, and then when it moves it drops to 2MPH...It shows 4MPH when the driver is forced to move into the lay-by, after stopping - this should be more like 1MPH...
Agreed if this had been showing 40MPH then I would suspect that the car was speeding, but currently I don't see any cause for concern.
And this is why the police will not prosecute unless excessive speed is indicated, too many variables in play to ensure accuracy regarding dash-cam GPS.
So any argument regarding that the driver was speeding, unless you were behind that wheel, there is no validity to your argument I'm afraid.
had u been driving at 30 the porky most likely would have made it into the gap between the 2 lines of parked cars on his side of the road and there would have been no issues.book a day at Silverstone if u wanna put ya foot down
