I thought those things measured like moisture or co2 levels or something science like just so you couldnt have a reverse engineered hacked vacuum blow in to it

Nope. Some of them now have required blow patterns to make it harder to trick. Usually blow and then suck when a tone sounds. The most recent versions include cameras to make sure someone is actually blowing and that it is the person sitting in the drivers seat and not a passenger.

lol why in gods name would you, sober passenger, blow into the breathalyzer for your drunk driver?

I work for a company that makes interlocks amongst other things.

Many passengers are idiots or, horrifyingly, some parents get their children to blow into it for them.
