Easy, all dogs are democrats.
Good point. Maybe she was jogging back. Didn't Condidit have a "no cell phone" rule?
Humans shed millions of microscopic skin cells (called rafts) on a continual basis. As a person moves along, these particles leave an invisible trail that is detectable to a dog. Some fall to the ground or catch on blades of grass, trees, or other obstacles, while some are carried along on air currents. The closer the dog is to the 'victim' the more concentrated this trail becomes.
In light of this, I would say, yes, she got in a car if the trail ended at the corner.
