While parked in neutral, with the emergency brake on, and no occupants, our standard transmission vehicle rolled backwards out of our driveway, across the street & into the yard across the street. Our driveway has only a very slight grade (less than 5%), so I'm alrarmed with the ease with which this happened. There were about 8 children playing around the street & yards. My neighbor & I both confirmed that the emergency brake was in the upright position, which I always engage before exiting the car. We do not know if there is a problem with the emergency brake itself, or if I simply did not pull up enough on the brake; however, if this can happen to a safety hound like me, I'm assuming I'm not the only one & that it's a common enough occurence to warrant some kind of indicator to alert the driver as to whether the parking brake is actually engaged.
