On the subject of driving -- the California Department of Motor Vehicles is making videos for YouTube – and the infamous bureaucracy also has a MySpace page. DMV is the nation's only state motor vehicle agency reaching out to younger drivers via YouTube. 55 educational videos on a variety of topics, include Top 10 Reasons for Failing the Driving Test, Maintaining Control of Your Car if You Get a Flat Tire, and – not to be missed --  How Not to Get Hit by a Light-rail Train. Beginning drivers can prep for their behind-the-wheel driving test, right there on the popular Internet video website. DMV officials say they hope to reduce the state's 50 percent failure rate for first-time test takers. The state is experiencing a historic teen population boom, peaking this year at more than 600,000 16-year-olds, the riskiest drivers.
