I'll talk first, if I may. One of the things I've been saying for about three years is it's very important that any application for funding for new infrastructure, for transportation or transit, include an evaluation of the impact of autonomous vehicles.
Anthony Foxx, who was the transportation secretary in the Obama administration, wrote an article, which was published in a magazine, that said full deployment of autonomous and connected vehicles can in fact increase the traffic-carrying capacity by a factor of five, which is huge. With all due respect to former secretary Foxx, I don't believe him, but if we could increase the traffic-carrying capacity even by a factor of two, that's huge. For the long term, I wonder how much of all this new infrastructure we really need. Some of it is justified. Some of it may not be. I've been recommending that all applications for financing for infrastructure carry that evaluation of the impact of AVs.
