It's harsh.. yes. But, it would get to the REAL problem... people who are driving while REALLY drunk, and are repeat offenders. And, it would get away from criminalizing people who are NOT the problem...
If the laws were clear, and severe..... people would adapt. They do in other countries.
Yes, and then why not introduce the next absolute law, to clear up the next horrible problem afflicting mankind? Are you so blind that you can’t see where this leads? Are you?
