Why use less reliable proxies like breathalizers to gauge impairment when we now have the technology to measure it far more directly: convert traffic cop cars into mobile virtual reality driving simulators. Put a gaming laptop in the trunk, and the DWI suspect behind the wheel with a VR headset on and let them drive through a couple of minutes of reasonably challenging simulated traffic. Let software come up with an…

Seems like we should care more about driving impaired than about driving under the influence. The former is what we're trying to prevent by policing the later. You can be impaired without being under the influence, and under the influence without being significantly impaired.

I don't disagree, but I've had moments when I was a terrible driver: I was tired, I was pissed off, I was stressed, I had just received bad news, I was quitting nicotine, etc.

I've done that too, and I should have been busted for that too. Is it really better to risk other lives due to lack of sleep than from too many drinks? For some stranger's little kid in another car's back seat, impaired is impaired.

You're describing a fancy field sobriety test. There's a reason why those who fail field sobriety tests for alcohol are then asked for a breath sample (or when they refuse, a blood test) A criminal defense lawyer would tell their clients to say in court they intentionally failed the test. (Burden of proof still lies with the prosecution) You can't be convicted for failing a test. You can only be convicted of being un…

I read something (a legit study IIRC) that breathalyzers are not that accurate and if you don't hold them right can increase the BAC.

And NO you CAN be convicted for failing the test. The evidence is just a paper reciept from the breathalyzer.

The reason you choose the blood test is so you have evidence for later.

Also you will sober up a little while you wait.

By that standard, that stranger could be arrested for careless driving because the child in their back seat was screaming for a juice box and they were allowing themselves to be distracted.

I have no idea legally how this would work, but is 'proving' impairment using your proposed method enough? I would think the missing piece would still be linking impairment to a substance or condition that the driver knew about, but drove anyway. ...which is why a simple sobriety test is typically given before a Breathalyzer.

We should care more about getting incapable drivers to stop driving than detecting insobriety. We should want safety police, not morality police.

And strictly on the morality angle, I don't think driving drunk is more culpable than driving over tired or over angry. I find those things are about as easy to detect in myself as drunkenness.

I believe there was a case in Colorado where a medical Marijuana user had enough THC in their blood to be considered impaired but they were able to pass a field sobriety test so they weren't convicted of a DUI. The problem is that the amount of THC you need in your blood to impair you is different for every person so it's hard to develop a test for it. A driving simulator makes sense to me, though once you have a bunch of adrenaline kicking in and are totally focused on not going to jail, you may perform better than when you are relaxed in the comfort of your own car.

To be clear, I mean no one is being convicted of failing a field sobriety test with no breathalyzer or blood BAC results.

It's an interesting idea, but the critical issue with it is that it's not illegal to be bad at driving. That could change, but that's how it is now.

It'll illegal to drive dangerously though, surely. It's a test that removes the license to drive from those who can't drive properly, whether due to old age, eyesight, drugs, tiredness. Only self driving cars for you.

The tests for obtaining a license allow for multiple attempts, and are administered by officers trained for that job, and aren't based on a video game installed in a cruiser.

> It'll illegal to drive dangerously though, surely.

Yes, and for all but the worst offenses (say, 30+ miles over the speed limit) the penalty is merely a fine and points against your license.

It couldn’t be any worse than “specially trained officers” who are able to detect whether someone is high by thier mannerisms and arrest people who aren’t using anything. https://www.11alive.com/article/news/investigations/the-drug...

That article is completely terrifying. * I am much too much of a control freak to ever ever try drugs; no moral issue, just not for me. * I have a drink of something on social occasion maybe once or twice a year, maybe not. Never got behind the wheel with even a sip of alcohol that day, let alone a glass, let alone anything approaching legal limit. But I'm a klutz and I'm an introvert and I get nervous easily and I h…

You can opt for the breathalyzer in most states, or they'll take you back to the office for a blood test.

If they take you to the office though they'll probably tow your car as a little extra bit of "fuck you" for exerting your rights
