No one eats in the vehicles period. Best part about it is the kids do a fantastic job caring for the cars. Bring them up right and they understand caring for things is one way to show appreciation and gratitude for the work that people around them put in to provide for them.
Also, if I ever transport food I notice the scent goes away super fast with the ambient air ionizer. X7 still smells like the day it came home and it's over a year old.
