You must have been the top scientist on the committee.

Video taped Driving Tests have been done for years. After moderate dosage drivers obviously lose concentration and coordination. These scientists are no better than the so called global warming scientists. And that is all this report proves. You are gullible to believe it, but it obviously fits your needs.

No necessary contradiction there - maybe the road drivers simply weren't dosed to that level, or maybe the videotaped closed-course tests failed to capture some relevant aspect of real-world driving.

These scientists are no better than the so called global warming scientists.

Aaand there it is: some bad science has been done, so any inconvenient science can be assumed bad with no further thought. You have fun with that.
