And why is so hard to build new transportation infrastructure? \n\nRobert Poole is the co-founder and director of transportation policy at Reason Foundation, and the author of Rethinking America\u2019s Highways. We talked about congestion, variable pricing, light rail, tunnel boring machines, and why they don\u2019t seem to work in our cities \u2014 or rather, why we won\u2019t let them work \u2014 and the infrastructure policy our politicians craft and pass that seems to be crippling us.
