When Kelly stops the car to get into the backseat, it is either in park or in neutral with the parking brake on, as it does not roll anywhere despite being on a down grade. When she gets in the front seat, she moves the shifter from neutral to reverse. In a modern car with an automatic transmission, this is impossible to do without pressing the parking brake and pressing the lockout button on the shifter. Had the car gone into reverse, it would not have rolled forward, instead it would have likely sat still or possibly begun slowly reversing. In either event, the autocall feature would not have been triggered and she would never have met Jeff.
