I've not seen one with a camera before but it would take multiple very large balloons, and a level of coordination that a drunk would not have.

You have to breathe out for a full 30s strong or it will error. It was suprisingly difficult. Then every 10 minutes while driving - it will beep and you have 2 minutes to blow into it or it flips out, and the car shuts off. You won't be able to turn it back on without contacting someone.

Actually it's fucked up thinking about it now....
