Or can be abused, without pet, to go directly to your desired floor without being interrupted by those passengers at other floors.

In Japan, where this pet mode exists, honor and respect of social rules are something, and I doubt you would take the risk to be seen leaving an elevator in pet mode without a pet.

Does a Tamagotchi count? ;)

Some destination-dispatch systems used in high-end residential towers will not schedule pet owners and non-pet owners to the same cab at the same time. Which makes a lot of sense.

I'd expect it to be more of a problem having multiple pet owners in the same car.

Well you have dog-phobic or people with allergies for neighbors.

Yes, I have a slight allergy for most of my neighbors :-)

> Pros

> Does not infect other passengers if the animal has an infection

I'm glad that elevators are concerned about such a scenario.
