Maybe the parents and child are smarter than your typical sue happy Americans and can take care of themselves and have fun doing it. When I was a child I loved to ride in the back of the pickup and my parents were responsible enough to drive safely. Troll on little people.
@ John, Even if the parents drive responsibly, they can’t control how anyone else on the road is driving. Good drivers get into accidents all the time because of other people driving stupidly, and if that happens here, kid in the back is seriously injured or dead.
I grew up doing the same thing in a way. But in my case, I was either sitting in the back of a pickup going down the road. Or the few times I was in the trunk, it was to hold what my parents had bought. And had no room in the rest of the car. Plus no rope to hold the trunk shut.
