I am a visual person. Maps always help me better than verbal directions. After watching this clip, I think I might have the guts to change my flat tire some day. I like the features available on YouTube such as rating, duration, time posted, number of viewing, and esp. closed caption. The only downside is that you have to watch some commercials, but it's reasonable considering the fact that everything is free.
