Of course, the NTSB is presenting statistics without context. That's what it's all about (Speed kills! Look at all these accidents where the driver was going over the speed limit! We won't talk about the percentage of drivers that are being counted in this stat that were going 5-10 over, or the percentage of drivers who go 5-10 over the speed limit at all times, because that context would kill our argument!)
I'd honestly rather see the limit made 0.0 than 0.5. It's more honest (though this would be a crippling blow to the restaurant and bar industries). I also think a random BAC content taken during a traffic stop is a poor measure of how impaired an individual is.
Citing Europe as an example for what America should do for its drunken driving laws is pretty stupid, though. In Europe, mass public transit is cheap and widely available. Things are less spread and spaced out.
It's an apples and oranges comparison.
