I don't think any jurisdiction has passed a law, a criminal law, which puts such a burden upon an accused. But what I can tell you is every time they make the penalties harder for drinking and driving, people fight these things harder and harder. The most significant amendment in increasing penalties took place a couple of years before I was called to the bar in 1985, where they changed it from a three-year minimum suspension to one-year, not criminally, but through the Highway Traffic Act, and that created an industry of “impaired driving” lawyers in Ontario, which has steadily grown since then.
The harder the penalties, the greater the consequences of criminal convictions, the more people fight these things. So when you make the penalty harder, people don't say, “Okay, you've got me. I'll take my lumps. I'll get a criminal record. I'll make sure I can't be bonded. It may affect my travel to the U.S. When I get my car back after I don't drive for a year I'll have to install an interlock device, and my insurance is going to go up to $30,000 or $40,000.” They're not going to say, “Okay, you got me.” They're going to say, “Gear up. Do what you can.”
