Q1.
It’s an urban myth that you can drive too fast to be caught on camera. It is, however, correct to say that over a certain speed the vehicle will not appear in the second photograph, but this simply proves you were driving well over the speed limit. Even if you had driven over the secondary check marks at 140mph+, your speed will still be registered from the first picture and as you’re out of shot, you’re obviously over the limit.

This will result in a court appearance and a driving ban.
