Perhaps those who are truly guilty don't know the ways of the Internet???
Maybe. Regardless of guilt, I suspect a lot might just want to forget the whole thing ever happened.
Maybe the guilty ones are shot in the back of the head in the courthouse parking lot. 
Perhaps I wasn't clear enough with my topic.
Guilty or not, thousands of people thus far have gone to court to defend the charge. However after researching the subject for several hours I've only found a handful of accounts from people who actually went through the motions. The rest consists of opinions, sometimes very enlightened I must say, on why the law is good or not good.
I don't think a JP cares if the defendant agrees with the law or not; seems to me every paralegal will say he or she can do something to help; it's not the officer's job to give a roadside course on what to expect next after impounding the vehicle.
Therefore, the best people to say what actually goes on after getting charged under s.172 are the ones who have had it happen to them (or people close to them who are in the know).
There is no shortage of "help me I was caught speeding" messages floating around. It would be interesting to know what happens next.
Good day to all.
