One thing to note, As you approach the camera's the do not necessarily work in sequence as you approach them 1, 2, 3, 4 etc, They could be the first, 2nd a dummy, 3rd, 4th, 5th a dummy,
So in that scenario you changing lane between 1 and 2 then back again for 3 has done nothing to help you 'get away with it',
Easiest solution is dont speed, not hard and stops you looking a twat when your trying to be a clever cunt
