5. Apps may be part of the solution, but they're probably just a tiny part. In today's litigious climate, it would be irresponsible (and unwise) for Apple, Google, and others to avoid keeping an eye on the apps built for their operating systems. But their due diligence isn't going to solve the real problem of drunk driving. To do that, you'll need new and sometimes controversial automotive technology: in-car breathalyzers, for example, or even cars that drive themselves. Driver education can't hurt either -- nor can friends looking out for friends.
Bottom line: No one would argue that apps showing DUI checkpoints are a good thing. As civilized people, part of our social contract involves respecting the lives and well-being of our neighbors, so until drunk driving ceases to be a concern, checkpoints are probably a necessary evil. But while censoring apps makes feel-good headlines for politicians, it doesn't begin to get at the root of the problem.
