Make cycle awareness a core part of the driving test

All the good practice goes out the window after the test?

Yep, sure does. I drive on the road every single day and don't see much good practice. And the drivers that have most recently passed their test are more likely to be in an accident which clearly means they are not following the good practice from their lessons and test.
If all drivers drove as if they were on their driving test how many accidents do you think would happen and how would they happen?
