We have examined the technology and the type of reports it can do. It is really wonderful. Of course, the cost of the system implemented in the United States is huge. At any rate, 60% of CN's locomotives have this system, since they operate in the U.S. They therefore must have those systems, which are really amazing in terms of safety. That is a big step forward.
In terms of voice and video recorders, let me draw a parallel with the Beta recorders back in the day. If those were sold in stores today, we would miss the mark, which is to increase safety.
That's more or less what I think.
