Breathalyzers have to be calibrated, 60 day interval for most interlock devices. Somewhere in the $20-40 range each time. I'll ignore the inconvenience since I suspect authorized calibration locations would pop up everywhere... at every gas station or something? I guess that would create an industry that a pioneering company could monopolize, haha. You also have to build in the cost somewhere... a discounted rate for a yearly plan as part of vehicle registration maybe, and of course you can pay out of pocket otherwise. But with inconvenience ignored and cost covered...
What happens when your breathalyzer is out of calibration?
Do you get a grace period after which your car will not start?
Does it never disable your car but you incur a penalty of some sort if you continue using an out of calibration device; fines, points on your license, license suspension?
- These penalties always get tied to the registered owner of the car I assume?
Is there 24/7 customer service in case of a breathalyzer hardware/software failure?
- What if your breathalyzer fails at a gas station on I-10 in the nowhere of Texas?
- Can you get a manual override (assuming you have phone service, and somehow prove you're not intoxicated)?
-- This would also mean your breathalyzer has a connection (cellular I guess) through which it can be reset/overridden or whatever.
These are concerns with the interlock devices in use now for people with a DUI. But they are collateral concerns stemming from needing the interlock in the first place because of a DUI.
And if we're at the point of the breathalyzer needing to be connected to handle some of these concerns I would say just put the camera in my car. Let it use algorithms to detect common signs of fatigue/intoxication/inattention/whatever. This detection can be done without a connection to anything, even if that's not likely. I would rather have a connected camera (even one that needs to record/analyze a short video of me to start the car) than have a connected breathalyzer. Both of them will have some type of downloadable history that can be checked in the event of an accident. And even without a connection the camera can perform continuous or periodic checks of the driver, as is the case now with existing systems.
