This happened in South Africa.
From the video description:
"We arrived home and as our gate opened, our small dogs ran out towards our car. We had to stop so that I could pick them up. I managed to pick up one of them into our vehicle but I had to then go beyond the car to fetch the other dog. At this point, I looked to my left and saw a vehicle racing down the road towards us. The vehicle suddenly stopped and that's when the attacker jumped out of his car with a gun. I immediately jumped back into our vehicle and as I closed the door my husband was already prepared in reverse and simply put his foot flat down on the accelerator."
