Every determination of what is safe is dependent on data. If we don't have data, we look at what public expectations are. That's true of any decisions we make regarding safety, whether it's a snow day or whether it's how we assess walking hazards so that we can make exceptions due to walking hazards. When we do route audits and determine whether an operator is in compliance with his contract, there's always an estimation and a balance between what our stakeholders would expect to be reasonable under the circumstances and what would be unreasonable.
When we start looking at the cost of any of these kinds of decisions, it still falls into what would be considered reasonable and what's unreasonable. At the end of the day, it's the parents and the government that will work together to decide whether safety belts are more important than the provision of transportation to a greater number of students.
