My blog has a series about how to write good fanfiction. Good, quality fiction should be like this episode. THere'wasn't anything overly pressing here, just teaching D.J. to drive, like would normally happen at this time, perhaps - as another fan pointed out - with memories of Pam's accident and the drunk who ran into her weighing on Danny's mind. He admits he doesn't drive like normal people, after all.
The writers got everything right, and while there's nothing overly memorable about this one, by letting the charaacters be themselves they did a very good job.
