Well you must have been indicating about 100mph you naughty boy.

You don’t say if it was a camera or whether you were stopped?
If you haven’t heard of
Pepipoo you will also find it a useful source of help and information which you may want to check out.
Chances are there is, or has been, someone with a case very similar to yours. They also have a
NIP Wizard but you would have to register, (for free), to use it.
I don’t go on there much and have never used the wizard because I never
ever speed.

In fact it sometimes feels like I'm the only one who doesn't

Unfortunately "You will be branded a threat to society by going over a speed limit where it is safe to do so, and suffer the consequences of your actions in a way criminals do not, more so than someone who is a real threat to our society."
Of course if you were doing it in a dangerous place/time/situation

you deserve to hang
Best wishes and take care.
