SF traffic fatalities have not been increasing year-over-year. You can't cast blame for an outcome that doesn't exist.
Data: https://www.chp.ca.gov/programs-services/services-information/switrs-internet-statewide-integrated-traffic-records-system/switrs-2020-report https://www.chp.ca.gov/programs-services/services-informatio.... SWITRS hasn't published a report since 2020 due to the pandemic, but that works perfectly fine for my purposes because I'd have probably had to discard those years for other reasons, and since we're talking about a ten- or fifteen-year trend I'm perfectly okay coming to a conclusion based on data from 2011 to 2020. Traffic fatalities per city are in section 8 chart E.
Fatalities have also not been increasing per mile traveled. Data: https://vitalsigns.mtc.ca.gov/indicators/daily-miles-traveled https://vitalsigns.mtc.ca.gov/indicators/daily-miles-travele...
I choose traffic fatalities as the metric because federal and state reporting laws mean that these numbers will be effectively complete - there is no sampling or selection effect, unlike numbers about traffic enforcement.
- KennyBlanken 2y agoThe link you included is not to deaths per mile traveled, it's to miles traveled. Even if deaths are relatively flat, they should be going down as older, less safe cars age out of the fleet of vehicles on the road. As time goes on, a greater percentage of vehicles have better crash safety, ABS, traction control, better airbag systems, and 'driver assistance' aids. Make sure any stats you do cite include pedestrian and cyclist injuries, but note that exposure data for them is exceptionally poor, because they are typically not included in traffic survey data collected by contractors hired by the government to do traffic counts. Overall pedestrian and cyclist deaths have shot up, by the way, and are the highest ever. https://www.npr.org/2023/06/26/1184034017/us-pedestrian-deaths-high-traffic-car https://www.npr.org/2023/06/26/1184034017/us-pedestrian-deat...
