Can I just add one more thing, Mr. Chair?
We're currently developing some crossing regulations as we speak, and one of the things we had to do was come up with how many lives we believe we're going to save, and how much property damage.
The only way we can bring that regulation forward is to justify that we're saving lives and saving some dollars, so it's already accounted for in the process we have to use. If there is no saving, it's very hard for us to push that.
