2 Test passes this week, Got me thinking................

While waiting at the Sevenoaks and Tunbridge Wells Driving Test Centres - You never get used to those test day nerves!!!! - I got thinking:
Is the current Driving Test good enough?
Is it acceptable that UK drivers require NO Motorway training after the test, and cannot go on it before?

The current standard required for the test is a competent level of driving, An ability to show that you are safe on the road and a good level of control throughout.
However, there is very little in the way of improvement or monitoring following the test. The responsibility is with the driver to maintain a check on their health, eyesight and ability to drive.
Surely there is a need for occasional assessments, Motorway tuition and health checks.
With the current system of 10 yearly licences this provides the chance to keep driving standards up to par without huge inconvenience to licence holders.
This could be brought in by Insurance companies to reduce the cost of insurance.
