Don't get me started Howard!!!
For what it's worth the IAM have always taught "gears for going, brakes for slowing", which also requires a certain degree of ability when it comes to block-changing down the gearbox.
I would agree with you that re-testing is not a bad idea but the basic driving test only allows a driver to demonstrate basic vehicle control skills and a modicum of roadcraft. The current training system does little more than teach a candidate to pass the test - it doesn't teach them to drive in the real world.
