The appeal is children too young to drive can sit behind the wheel and "steer" the cars are on tracks though and the only aspect the "driver" controls is the speed. They sound and smell like ride on mowers.
I don't think the ride is worth the walk to it, especially in summer, nice nostalgia though.
