Mr. Creel, you talked about prevention and you said that you invest in improving technology, the human factor, training, and so forth. You mentioned changes in the culture of safety.
There are two parts to my question. I would like you to quantify your investment in the technology and in the human aspect.
As far as the technology component is concerned, you referred to cameras, but there is also the automatic braking system. You have refused to adopt that system in the past, and I would like to know why. I would also like to know how much it would cost to implement such a system.
