Couple of points of criticism:
"calculated" emissions from heated up cars idling compared to cold start cars, probably.
Also not fair to compare non drive thru to drive thru at different restaurants. Apples and oranges comparison.
Comparison should be for individual cars driving through and not. There is technology to test this. Why didn't they use it?
