Oh, top trumps, eh?
In that case please allow my to show you my Lamborhini Countach card - I'm a retired copper who used to teach advanced driving. That's proper advanded driving to coppers, not the watered down civilian 'advanded" which is actually a lower level than police "standard".
Indeed, I was taught to drive by my Dad who was a RoSPA instructor and I was a civilian gold certificate holder before I'd even passed my driving test (my first test was cancelled due to fog so the observation drive I had booked for soon after actually took place on L plates, dual carriageway taking the place of the motorway for this purpose.)
The most dangerous sector of driving society, in terms of the disproportionate number of smacks they have compared to their numbers, is the under 30s. They ace the over 70s by some margin, so if we're using the likelihood of of a driver having a smack as a yardstick then the under 30s should be retested every two years first.
I would agree that anyone who drives for work above and beyond simply driving themselves from A to B should hold a professional licence, with strict training to obtain it and penalties for abusing it. It's a nonsense that some of the worst drivers are "professionals", but hardly surprising seeing as they're some of the worst paid out there. Businesses aren't likely to attract either top talent or conscientious characters for the abysmal salaries drivers earn.
As a retired police officer you should understand that continuous assessment and training is required to maintain the required standard. The Police motorcycle riders I have worked with are clearly highly trained and excellent riders. The RoSPA examiners are almost exclusively retired police officers who give their time to help others.
Having cycled 55 miles today in Wiltshire and Hampshire including and one short section of shared footpath and cycle path i maintain that a large proportion of the car drivers do not understand the Hierarchy of road users.
I maintain a multi faceted approach is require, training is part of that, but so is physical separation of vunerable road users from vehicles.
