I'm generally pretty supportive of any attempt by a government agency to use the Internet to get messages out to younger people. The CA DMV YouTube page is no exception. The page is full of old (and new) DMV videos dealing with what you need to know to pass your driver's test, how to be safe around motorcyclists, and how to share the road with light rail vehicles (hello, Cheviot!)
The one complaint I do have is that driver's responsibility to watch out for cyclists and pedestrians is relegated to one video that lasts just over one minute. Maybe we should be spending more resources on reducing bike/ped deaths since the trend of declining bike/ped deaths ended four years ago.
