As I said before, a lot of the technology is advancing now as people are getting further along. Biometrics is a great example. The technology exists in some places now for you to walk through a gate, and computers will be able to identify you as an individual, just through cameras, and associate you with a ticket. You wouldn't have to go through a turnstile or show a ticket or anything. If you try to go through without that recognition, then a security guard can be alerted and come to resolve the issue with you.
I think the solutions, from the technology standpoint, will eventually come. They need, as I was suggesting earlier, some encouragement and some support to get them accelerated, but really that's it. Take a look around internationally. There are not a lot of legislated solutions that work. There are a lot of studies that show a number of interventions that have failed, price caps being one of them, but there are not a lot of great examples of ones that work, unfortunately.
