There actually are real world vehicles like that. They're very similar to autorickshaws http://theforeignchallenge.com/wp-content/uploads/2015/04/auto-rickshaw-challenge.jpg

I guess your example isn't the refered vehicle , (it has a bucket). But maybe we can say that car in zootopia is more like a mix of both vehicles, since it is more compact and round than an actual meter maid car, resembling your example.

An apart question: why do people give inaccurate names for objects? Motorcycle, by its etymology, would refers to any vehicle with wheels ("motor" = "that moves", "cycle" = "wheels"). A similar thought is valid for bicycle, tricycle and quadricycle, since the prefixes state the number of wheels and multiple distinct vehicles, beside those, have the same number of wheels.
