The question for me is not whether behavior after the T is different with or without the seatbelt. At this point, the penalty for the next T is the same either way.

The question is whether the seatbelt provides sufficient incentive for proper behavior prior the first T. In other words, is there a noticeable benefit to the way coaches behave before getting their first T in a game. The only measurable way to determine would be to count first Ts, not second Ts.
