Here in PA they use the plastic drums cut out like that to make a train (5-6 cars) for kids pulled by a lawnmower.
We were at a Christmas Light display at a nearby town park and they were going pretty dang fast and doing donuts near the end of the ride, the kids howled and loved it!
Also like when people use a Wheelbarrow bucket to make a Hot Rod style go cart. Or old school dragster.
