A bumper car earns its name when there are two of them on the same floor, which is why the pace is capped at 1.3 mph and the rim carries a full bumper strip. Contact stays a bump. The chassis underneath the molded panels is metal, because a toy designed to be driven into things has to survive being driven into things. Charging runs 8 to 12 hours, so it goes on overnight and is ready in the morning rather than halfway through the afternoon. Dual joysticks let the rider spin a full 360 degrees on the swiveling wheels, and a parent can take over at any moment with the remote. Seat 12.5 in wide, rated to 44 lbs.
