Hi everyone.
I just received a NIP alleging I was driving 80 on a dual carriageway. I went to check the evidence as I remember potentially being a bit over the 70 limit for a moment and then reducing my speed.
What I noticed was that the first picture shows a long distance picture of a car which looks similar to mine but the number plate isn't legible going at 80mph with a timestamp of 12:26:05 and D=0352.7m. The second picture has my actual car (number plate is legible) in a different lane to the car in the first picture going at 64mph with a timestamp of 12:26:14 and D=0079.4m.
I assume D is distance, so I calculated that the distance between the 2 pictures is 273.3m and that there is a difference of 9 seconds so the average speed over that 9 seconds is approximately 30.37 m per second which is roughly 109.32 km per hour or 67.9283 mph.
If I assume that the first picture is indeed my car, don't these calculations prove or at least reasonably suggest that I was in fact driving at below the 70 speed limit? Is this a reasonable defence?
Many thanks for any comments or suggestions!
