Continuity mistake: Miles only learns to drive in this episode, however, in the early episode "I, Busybody" (not aired out of production order), Miles fights a speeding ticket, indicating he had no fear of driving, knows how to drive, and has a driver's license.
Continuity mistake: When Sabrina is teaching Miles to drive he pulls over to park there is a street sign. The car's position next to the sign keeps changing.
Answer: There was never any explanation given about what happened to Miles or if the reported shooting had anything to do with him. He just suddenly disappeared. There is some indication he was written out due to the show undergoing budget cuts and reducing the number of characters.
