Federal Government trying to invent something that would be a giant waste of money? No way! They never do stuff like that. :crackup
I agree, just like when they decided to invent ignition interlock devices on vehicles for people convicted of multiple DWI’s (now I think it’s only one and you get one though). What did people do? Had someone else blow in the device so you’d get a good BAC and then the drunk person would drive.
A good friend of mine just recently got his first DWI and apparently the State requires you to pay to have a camera and the ignition interlock device mounted in your car so they know the person who blew in it is the person who should be driving.
