So am I to assume you are advocating a constitutional amendment allowing you to drive your 2 ton chinch of metal 60 miles per hour? If that's the case maybe you need to read up on current law. In Indiana the term intoxicated is defined as under the influence of a substance that alters your normal state of mind. Also in Indiana you are allowed to drive under the influence of an alcohol just so long as you are not over .08 BAC. So in Indiana there is a law that specifically states you are allowed to drive intoxicated, just not over .08. So it would seem they didn't forget it......
