VNX is correct in his summing up, that is why we have precedents and case law, laws are interpreted by the judiciary.
I refer you to the above SA ARR297, this has been used to cover offences such as 'burnouts'(the driver does not have proper control), through to the driver seat being reclined too far and the driver not being able to reach switches, indicator stalks etc, (lack of proper control).
A law can't be precisely written to cover every 100's of possibilities, so it is interpreted.....and argued in court.
