> I would prefer that the change is to build a BAC measurer into every car. This is a technology that we have today, it is being used and it is efficient enough that it continues to be used. There are problems. Having to do a breath test in the middle of your drive. Can't drive after eating or brushing teeth. No mints or chewing gum while driving. Must be very careful with medications. Regular calibration. Vehicle service might require a certified technician to verify the device isn't tampered with. False positive means you can't get to work on time. Sharing a vehicle is much more difficult. This is a very high burden to put on the average driver who has done nothing to deserve it.
