Breathalyzer ignition locks ?
I know that in the USA these are used for drunken drivers. ( I think I saw it on '" My name is Earl.".)
Yesterday, listening to the radio, I heard a a UK politician propose that all new cars be fitted with these devices.
It made me think; could a balloon filled with sober air be used to fool the machine ?
Does anyone in the industry know ?; If so, it would seem a very simple loophole.
This is a fine example of a failed test.
