Derf:
What evidence do you have that drivers are being prosecuted for taking one hand off the wheel?The police are enforcing the law, it’s what they’re paid to do. Whether you agree with those laws is an entirely different matter. Point is, you wouldn’t have gone into road transport blind, you must have been aware there were road traffic laws in order to pass your test. If you don not agree with following those laws, or have a problem with how they are enforced, perhaps you should reconsider your career choice.
I would think that in order to eat or drink pick your nose/arse it would be an essential part of the process to take a hand off the wheel 
. With maybe the exception of the last 2 examples the Police have achieved their goal, thus nicking the driver. As for wishing to reconsider my career path(patronised again 
) we have finally found something we can agree on, after watching the industry over the last 30odd years decline to the over regulated farce it is today. (Oh,and before you ask I have no evidence/proof/lists that drivers are being prosecuted for picking their arses )
