that would never fly. once it's lowered, there ain't a politician on the planet who would be able to promote RAISING the limit. it's like how the legal age was pumped up to 21 thanks to reagan holding infrastructure money hostage against any states that refused to comply with the national minimum drinking act (which only popped up thanks to immense pressure from MADD). everyone knew it was bullshit, but once it got passed you'd never find a politician willing to stick his neck out for his opponents to accuse him of encouraging teenagers to drink.
if they lowered it to 0.5, it'd stay there. period. which means you could be 100% sober but if a cop claims you were swerving and you got metered at 0.6 thanks to having a single beer an hour before, now you have a DUI on your record. because that's how justice works.
There's no way you would blow. 06 after an hour on a single beer
We've had. 05 here for years and it's helped a bit
