The whole idea that vehicles in the future will communicate with each other is a really big deal. It's a big deal for safety... and it's an opportunity to engage the automobile in the work of ensuring collision avoidance.
As we look at a future where we're going to have to double our freight capacity, how do you create a freight system that's integrated across the country when you have 50 different freight systems that are built one state at a time?
You come to Washington, there's a rail bill, there's a highway bill, there's a aviation bill. But when you go home, there's an airport, there's a highway, there's a rail, there's transit. It all has to work together.
Tolling... has a place. We're not going to toll our way to prosperity as a country. It is a tool that can be used in some instances, for example, to add capacity and to pay for that capacity privately. But I don't think it is a complete solution to how we deal with our surface transportation issues.
