What is the purpose of the Vehicle Tour cameras?

Is there actually a purpose for them? Or are they just a decoration piece?
Can we make them functionable or at least more interactive? Maybe by bringing in a small profit boost towards the Tour Attractions?

Half the time I just forget they exist so it seems like a waste of a potentially good thing.

I think they are just decorations, they do not impact the game outside of visuals.

It would be interesting if including them in the tour would make the tour more appealing to certain guests depending on where it is placed, like having a camera placed near 5 or more species of dinosaur would make it appealing to nature guests, or placing them near carnivores would make them appealing to adventure guests. A few camera placements would then determine what kinds of guests the tour would attract.
