I can see why the next hearing is called a 'trial'! But it's trying the evidence rather than Patrick as a criminal (subtle difference?).
If we look at the case and assume that the OP Patrick is in fact totally innocent of what he is being charged with, it then might seem slightly ridiculous that a matter of a driver's hand supporting his head and singing is brought as far as a trial.
But we must also accept that the Police have innocently acted in doing their duty as they saw it - Reporting the illegal use of a phone while driving. However, by hearing all sides in a courtroom is how fair justice may hopefully be established. That is what is meant to happen.
Sorry, but I still have a niggle about the possibility of a Driving Without Due Care and Attention charge as it adds weight to the CPS case and it's unclear to me whether Patrick was actually driving while supporting his head (and singing) rather than only doing so while he was still stationary at the traffic lights. It also makes me think that 56OctyVRS's advice to get a solicitor is very good advice. I would suggest a specialist such as Patterson Law:

One thing I can strongly advise from experience is that a
SPECIALIST solicitor/lawyer in
ALL cases is an absolute must! The technicalities of law are mighty complex and not necessarily related at all to emotional judgement.
