Provided one is not off to an event where the odd bit of stubble is of consequence, a shave can be carried out with ZERO of the conscious part of the brain in use. The last little bits of stubble may require conscious checking and dealing with. For safety's sake, thes have to wait until one is parked up.
And, as he passes or otherwise observes you, how is a copper supposed to know you are only using the part of your brain that you believe can do the task without compromising your ability to drive? Does he wait until you collide with a parked vehicle before determining that you've now moved onto the phase that requires conscious checking? Whatever happens, the police in the real world have to make a judgement and act accordingly. I'm happy that the shavers, lippy applyers, readers, writers etc are being pulled.
Furthermore, how do we know these secondary activities don't cause crashes? Would YOU admit you were having a shave if you collided with a car whilst doing so and had the opportunity to dispose of the 'evidence'?
Higher level overarching aims are all well and good, but road safety still has to be enacted in the real world. What works in theory cannot always be readily applied in practice and we cannot have individual driving plans that permit certain activities when conducted by one person, but not by another. I know this doesn't sit well in our 'tailored to the individual' society, but its a best fit IMHO.
So, I'm happy that engaging in a secondary activity not directly related to the process of driving is a good enough metric for both attitude failures and potential control failures. I'm happy to let the police make the call and realise that there is an element of subjectivity involved.
