I have some very long paths in my parks, but only a max of 6 trucks and 10 spheres. So the fact they can cross multiple exhibits and long tracks causes very poor density of vehicles for viewing.
+1. It would be nice if they made it so the amount of max Gyrosphere/Trucks you can have scaled with the length of the track, for example getting an additional truck/gyrosphere every 500m or something like that.
