The American government needs to get much, much, much smarter about cycling safety, the National Transportation Safety Board concluded this week, during its first evaluation of the issue in almost half a century. The feds should help cities improve infrastructure for people who bike, to prevent fatal collisions with cars, the NTSB panel found. Regulators should require vehicles come with cyclist-friendly safety features like brighter headlights. Most controversially, the panel said that all states should require all cyclists to wear helmets—a suggestion that has long rankled bicycle activists.
