Forgetting to Apply the Parking Brake

Occurred on January 7, 2019 / Webster, Massachusetts, USA<br /><br />Info from Licensor: "I exited my vehicle, and as I grabbed my things from the passenger seat, I forgot to set my parking brake. As soon as I entered my house, the car began to roll backward and ended up at the curb of my neighbor's lawn. Another neighbor that happened to be driving by honked politely until I came out and realized what had happened."
