Since finishing the Interstate Highway System in the 1990s, the U.S. has added 75% more urban highway lanes — and we're on track to double it again. Erick Guerra, author of "Overbuilt" and professor of regional planning, joins Chuck to discuss why we can't stop building highways we don't need and how our transportation funding system creates cities that are more dangerous and less prosperous.
