A number of times I've felt okay to drive, but questioned whether I could pass a breathalyser, so I handed the keys to someone else. It's really quite simple to not do something illegal.
The problem is that so many people do it daily (driving while under the influence), not because they want to drive drunk, but because they think they're still OK to drive. Others do it because they want to avoid the hassles I described. I wish more people had sense enough to say they shouldn't drive or plan accordingly (designated drivers, I hate driving others around... but I'm always doing it). The reality is we have the laws to handle this stuff, but they're usually authored by people in the pockets of the industries the laws affect and are slanted in favor of business and money. I never said make it illegal, I just believe that the current laws (and licensing of liquor sales for a fee and higher taxes) places local governments in the money making business instead of the public safety business where they should be... To say you can't have apps because they allow you to pass information to other people about where things are going on is just stupid, like many other things that the sheltered lawmakers of our country do. Next it will be websites with active HTML5... then they'll put pressure on the hosting companies? DJ's can't let people call in and report where police are? Where does that stop?

The point still stands; We as a society encourage people to consume things with deleterious effects away from home, and then get upset when they get on the road. Work special events for 10 years and then tell me after an event that had 30k on the grounds, that thousands of them didn't leave there above the legal limit and drive home. There's many fences, gates, light poles, and workers around the local venues to tell you other wise. It's about the money, not the art of making drinks. How many places in an event can you get a mixed drink, vs. beer? If mixed/specialty drinks were all that were allowed away from home, it still wouldn't be good enough. People would abuse that too... because they can. Again, people and their inability to control themselves and make good decisions while sober (like knowing how much of something they can consume and not go over the limit), just leads to them making even worse decisions when they're not sober (when they keep drinking and then drive). There's no need to enact additional laws, just stop issuing/renewing liquor licenses for places that breed the drink and drive behavior. There's a reason, most locales can't have drive through liquor stands.
Our government should be working on major issues instead of trying to make themselves look good by strong-arming distributers into not allowing legal things to be sold. Guns are not banned because they're attached to the constitution and they're are major lobbyists groups who'd like to keep it that way. They've made radar detectors illegal in some places, and even actions between consenting adults... Next it will be CB's which have been letting people communicate where speed and other traps are since they were first sold. I know a few people who use all of the above and any method they can to avoid check points and places where they're are lots of (or hidden) police to avoid being harassed just for being out. The services are either legal or they're not. These lawmakers are just going after (pun intended) low hanging fruit. It makes them look like they're doing something, when in reality it's pretty much useless. This isn't as bad as Congressional hearings on drug use in baseball, but it's in the same... ballpark.
Wow... ramble, butit'll have to do.
