​Stop Drive-thru litter by printing the number plate of cars ordering fast food at the drive thru on the bag.

The litter around drive thru restaurants is so disgusting. Why not make people take ownership of their rubbish from the drive thru by printng the cars number plate on the bag when they order their food? Most drive thrus have automatic plate readers already so it wouldn’t be particularly expensive to implement. I think it would make most people think twice before littering if they knew it was potentially traceable back to them!
