When I write these little features, I always follow a set of self-imposed rules:
Rule No. 1: The car is always the main character;
Rule No. 2: Avoid using the same personality profile as in a previous story;
Rule No. 3: Inject truth. Use real ownership experiences for each example, and plausible explanations for clues;
And, Rule No. 4: Avoid blanket, prepared or generic scenarios.
I’m going to bend that last one a little bit. I’ve found the right example to illustrate it.
