Certain heists such as Watchdogs and Rats Day 3 have two different vehicles that are generally available at the same time. One is indicated to the player as a loot securing vehicle, and the other is indicated to the player as an escape vehicle.
Can loot be secured by taking it with you to the escape vehicle, even though the game doesn't offer a "loot secured" text alert?
I see three scenarios that can be tested:
Loot is secured in the dedicated loot vehicle
Loot is on the ground in the escape area
Loot is on a player's back who is in the escape area
