This would be extremely efficient for completing route tasks, you could actually swoop around and pick them up while waiting at a stop. I realize not all of them would be accessible this way due to camera limitations, but it would still be very helpful. You can already couple/uncouple cars in the same fashion, so why not?
Would love to see this added. Currently doing the collectibles for Sherman Hill and its just taking forever to get them by running around. Even with a guide to find them all.
