I can answer the question.
MADD Canada and MADD U.S. sit on an international group with the car manufacturers, and we're working on a non-breath-invasive test to determine blood alcohol levels. Basically, for Canada we're looking at the 0.05 level. If the person is below that level, the car will just start; you won't even know that the technology is there. If it's above 0.05, basically the ignition of the car would not be able to start it.
We're hoping, through this blue-ribbon panel, to have a prototype in cars within a couple of years and hopefully available to fleets and various rental cars within the next five to seven years. The science is there, it's realistic, and the car manufacturers are most willing participants, but in the meantime we need to address some of these other issues.
