isn't this so typical of casa's crap approach.
the requirement is a simple drivers licence.
casa just cant let go of the bull****.
we have to have a special driver's licence certification under instrument blah blah.
for gods sake casa give it a rest or you'll go blind.
it is all bull****. realise it and let it go. the guys are quite capable of seeing a doctor and managing their health without all your casa embuggerance.
