Yes. As you say, Australia has been for many years, and I know New Zealand, France, and other countries have been using these devices and have had very good results. There's a culture and a mindset there that they treat drinking and driving differently than we do in Canada.
We've had friends from Europe, and when they come here, if they go for dinner and have a drink, there's no way. They say you can't drive back home. That's just the culture. It's a different mindset. They can't believe that we allow drinking and driving here in Canada, after so many countries in Europe and elsewhere don't allow it.
