Why is the Ladybugs considered a coaster?

My home park in Des Moines, IA is Adventureland and according to alot of sites the ladybugs is considered a coaster on their list for my park. My question is how come a flat, kiddie ride is considered a coaster. If is is than that means that the ladybugs attraction at SFGAM should be considered one too.

Assuming this is a standard Ladybug, it should not be considered a coaster. While it follows a track and goes up and down hill, it is under continuous power and does not "coast".
