Taxes pay for stop signs, and yes before you correct me, we all pay for them. You completely miss my point. There are many ways to stop drinking and driving. They already have breathalyzers that wire to your ignition. They already have tech to electronically test the air without you blowing into a tube. Much cheaper, easier, already developed, and less invasive. But it doesn’t give you eyes into every car on the road, and that is the end goal, not your safety. If you think this is truly about the safety of anyone, you completely missed my point and in my opinion are either a bit thick or just trolling, my guess is a bit of both.
