What funny things happened while driving?

Once it was my brother-in-law's car. I was sitting in the back row and my nephew was sitting in the co-pilot. We walked to the door of a convenience store, and my brother-in-law got off to buy water. There was no handbrake at that time, but the car just heard an uphill place and slipped away. At that time, because my nephew and I were still young, we couldn't drive and didn't know how to pull the brake. We cooperated. My nephew opened the co-pilot's door and stretched out his foot to slip away. I jumped out of the car instantly, ran to the bottom of the car and got off the cart. I really panicked at that time, but fortunately, the speed was not fast and it was still under control. But it's really scary to think about it now. If the speed is faster, something will happen to my nephew and me.
