they said that feces was found in the seat, which Morgan says was there before she got in.  Why the fuck would you get into a car with shit in it? A normal human would just refuse the ride and call a different driver. At this point, this person either shit in someone's car and is too embarrassed to admit it (most likely explenation) or didn't have a problem riding next to a pile of shit without mentioning it to anyone. The latter is actually a more disturbing possibility.
