Senseless (Bicycling)

The concussion rate from bike accidents in recent years has grown faster than the sport of cycling. Why?

LaHood: expect big announcement from Obama on transportation funding (Governing) 

The outgoing U.S. Secretary of Transportation hints that perhaps the President may have an idea to replace the federal gas tax which funds many projects but has been struggling to keep pace with demand (the tax hasn’t been raised in 20 years and is also taking a hit because cars are more fuel efficient these days).

Or congestion pricing lanes sometimes or all times?
