My Monday morning (Tuesday lunch) quarterbacking:

1) Went into labor unexpectently - Can be somewhat anticipated, but not really something you can schedule. Mine decided to show up a month early, so I can't fault her.

2) Going down an unknown, rarely used, back road while in labor - First mistake.

3) Not having enough gas to begin with - Second mistake

4) Giving birth in car by herself - Kudos for her fortitude and skill.

5) Not planning for getting stranded - This appears to be in a rural area, so...Third mistake. I'm not sure about the air and ground coverage, but this would seem like a good time for mirror and whistle work, and GHB provisions.

6) Forest fire - Kudos on the idea of a signal fire, but points deducted for choice of location.
