The breathalyser test (for all intents and purposes) proves guilt or innocense. The technology isn't all that complicated! If you think not submit a citizens bill to have it otherwise!
No it doesn't. If it did, nobody would be able to beat a charge of blowing over.
As a side note, do you understand that blowing over the legal limit and impaired driving are not the same thing?
Umm, the logic there escapes me. I think the figures of economics would dictate driving is more important to people's lives than drinking. Would eliminating driving be fair to the person who doesn't drink? Do ALL our rights supercede another person's right to live?
People can be impaired for any number of reasons (lack of sleep being one of the most common). The only real solution is to ban motor vehicles. For gawd sakes, think of the children.
