That study [0] had so many flaws it's not even funny.

1. It only had 12 participants 2. One of those participants was excluded from the final results 3. They didn't test the participants' (or a separate group's) driving ability while under the influence of alcohol (they used a simulator, so it would have been fine), and so you really can't use the results to make any comparisons between dehydration and alcohol use 4. The study was funded by the European Hydration Institute

I kind of love that biased test results funded by Big Water are a thing.

Oh trust me, "Big Water" is very much a thing. I've met a guy who runs a coke bottling plant; he could hardly believe his luck. They literally just run the existing stuff dry, and it's got massive margins.
