>Also those are super easy to defeat. people have defeated driver awareness systems with flat-printed pictures of their face. I don't know if defeat-hardness is a particularly good metric for these kind of systems. Very few systems on a modern automobile haven't been defeated in some way/shape/form. I think it's more valuable to consider the convenience or life-altering-aspect of the consideration -- few people mind nor even notice their photo being taken, forcing folks to breath into a breathalyzer changes their activities and behavior ; their routine is now disrupted, that's a hard sell. ( I hate additional surveillance options, espescially given the idea of the 'always connected automobile'; it's a system that is prime for abuse by authorities. My consideration of these features in no way implies that i'm happy about either implementation. )
