Don't know if there is an agenda or not, it's already impossible to find data that is acceptable to many, some won't accept anything, so I'm giving up.
I just know there is a problem by what I've seen and what I know about first hand.
I think we ALL know people who shouldn't be behind the wheel, PERIOD! But... life is like that.
It's a shame that better data is not freely available for everyone to see. What I concluded in 1985 was... policy-makers were not interested in factual data regarding true risk. I'd be speculating as to the reasons why.... but, times haven't changed much. Many of the same things apply to drinking ages around the country.. but, that's another issue.
