My commute in San Francisco involves crossing 16 streets. It's not very far, about 2.5 miles.
On Friday I observed 35 cars run red lights--not even "it's yellow and time to speed up because drivers don't give a single flying crap about safety" but literally the cross traffic lane is green.
Cars are a terrible unsustainable mess, ruining the environment and ruining city livability. It's not surprising that the risks they impose on the rest of the world are resulting in less people willing to bike
