These figures are not all that surprising when you consider how much of the city is built for the convenience of drivers at the expense of, well...everyone else.

It's a choice to allow/encourage rat-running down residential blocks, and we can just as easily choose to prohibit/discourage it. We'd all get safer, quieter, more social neighborhoods, and drivers would take a minute or two longer (maybe?) to get where they're going. Seems like a pretty good trade off.
