O.K. enough stone throwing and hyperbole. All kidding aside I did find a review of the Domino's Pizza lawsuits of the mid 1980s to have some very similar parallels to how some of us perceive this whole discussion. In the Domino's case it came down to perception:

A lot of other pilots here and the controller who started this thread seem to think that; Often, the cultural norms and the pay system over there causes too fast of a taxi speed to be used by WN pilots, too much of the time. Public perception.

The following is a direct quote from Domino's Pizza - Wikipedia, the free encyclopedia

"Starting in 1973, Domino's Pizza had a guarantee that customers would receive their pizzas within 30 minutes of ordering, or they would receive the pizzas free. The guarantee was reduced to $3 off in the mid 1980s. In 1992, the company settled a lawsuit brought by the family of an Indiana woman who had been killed by a Domino's delivery driver, paying the family US$ 2.8 million. In 1993, Domino's settled another lawsuit, this one brought by a woman who was injured when a Domino's delivery driver ran a red light and rear-ended her. The woman was paid nearly US$ 80 million. The guarantee was dropped that same year because of the "public perception of reckless driving and irresponsibility", according to Monaghan.[18]"

Let's hope that it never comes to anyone being injured by a corporate norm that encourages taxing too fast, because there is a mountain of evidence and a whole mountain range of perception that the behavior is prevalent and less than safe.

In the Domino's cases, it seemed that perception was far more important than the evidence.
