I always say this but people in this country complain about the guards not doing enough to prevent road deaths etc, we complain. If they introduce measures like this we hate it because it will hold our journey back 5-10 minutes at a little checkpoint.
I take prescription meds but they don't effect my driving. If I have to put a prescription slip in my glovebox, I'll do it. I'll fly through every checkpoint because if you have nothing to hide, you don't have to worry. It's not collecting revenue, it's just being a responsible adult and not breaking the legislation.
