while in approve in general, i'm worried by the inclusion of prescription drugs, and the total apparent lack of a fitness to drive test.
The nightmare scenario.
i am stationary in a queue of traffic.... and get rear ended .... the police drugalyse both drivers as a routine....
my results show i have high levels of codeine in the system.... which although these days i no longer take daily, i still take dihydrocodeine ,regularly for my neck which, to my metabolism, acts about equivalently to aspirin for most people...,
codeine is one of those drugs which in higher strength doses carries the drowsiness warning, and says IF affected you should not drive or operate heavy machinery....
i'm NOT affected ..... EVER........ but , it would seem likely to be one of the substances on the list....
so, i face a massive fine, loss of license, and possible jail time for taking a drug which enables me to operate normally..... as opposed to not taking it and being unable to move my neck.... thus restricting my ability to perceive traffic around me....
so, i would like to see the inclusion of a mental alertness test, or some other such means of determining whether the machine reading should be taken note of.
in other words, halfway between current situation, and the proposed solution.
on the other hand, the stoned/tripping/"fix happy" driver should simply be shot.
