Yearly delay: 70 hours
Cost per driver: $1,738 (Chicago), $1,555 (Washington, D.C.)
Chicago and Washington, D.C., each benefits from a strong public transportation system, so their congestion problem, while the worst in the country, would be even more awful without it.
Without public transportation in cities across the US, the amount of extra congestion would have cost an additional 785 million hours in time delays and $19 billion worth of fuel, the report estimates.
