I just ran across an interesting piece of data that I was not aware of before, in Motor Vehicle Crash Deaths in Metropolitan Areas — United States, 2009. Sacramento area ranks 8.3/100,100 for motor vehicle related crash deaths, but 14.4 for the city, which is in the middle of pack for the US, but worse than most of California. Riverside area is 10.6 and city 11.9, San Diego area 7.8 and city 5.6, San Francisco area 5.6 and SF 4.0 and Oakland 5.0, Los Angeles area 6.6 and Los Angeles city 7.7 and Long Beach 6.1 and Anaheim 7.8. This 2009 data, and I could not find anything from CDC more recent. For contrast, London is 1.6 and New York is 3.2, both considered dangerous places in the mis-informed public mind.
