A Chihuahua in Louisiana put an SUV into reverse while its owner was pumping gas, causing the car to roll backwards into a busy street. The five-pound dog managed to weave through oncoming traffic before the car crashed into a barrier at another gas station across the street. No serious injuries were reported, and police later found that a mechanical issue allowed the transmission to change gears without pressing the brake. Meanwhile, a black Labrador retriever in Florida also accidentally put his owner's parked car into reverse, resulting in a circular joy ride for about an hour.
