I think you are missing the point. I am not saying that all non drinkers are safe, I am saying that all Ryders no matter the skill level, are safer if they have not had anything at all to drink, than they would be if they did have a drink, and that my friend is just Science. The inexperienced ryder is still inexperienced, and potentially more dangerous, than the seasoned ryder. Now add alcohol to the equation and both the these ryders are impaired with regards to reaction time etc. These are two different pigeon holes if you will, the common factor is the impact of alcohol on these two groups. I know that this is true for me, and I am pretty sure that anyone on this board would agree, if you feel the relaxation effect of one beer, that same effect has impaired your ability to handle your machine at the same level you did before you had the beer. I am not saying that one beer makes you unsafe, I am only stating that the ryder is impaired once they have indulged. As for medication, 14 years in the pharmaceutical tells me that the warnings on labels are there for a good reason, and anyone using narcotic pain relievers, or antihistamines that cause drowsiness, should also not be operating vehicles either. In today's day ther is a plethora of non-drowsy medications out there that will not impair anyone, short of an allergic reaction.
I salute ute your enjoyment of a nice cold libation after a long ryde, and I would gladly join you one of these days. I am just not going to do on our officially sanctioned group rydes.
