My son was super active.Traveling with him was an adventure. Mom had a great big Ford station wagon. Kiddo would go from front - middle - back make a U-turn and start all over again. So my Dad made a fence that separated the back from the rest of the car. Kiddo was put in through the back window with toys and driving was less dangerous after that. You can imagine the looks we got. And a few Mom's actually wanted to know where we bought this wonderful gate. P.S. This was before the invention of seat belts and car seats.
