This was one of the presentations at the Silicon Valley Bicycle
Coalition Bike Summit.

Slide 6 is especially telling. No surprise that the U.S. has the lowest
number of bicycle travel in terms of distance, and the highest death rate.


How many of the US deaths were due to getting hit by a drunk driver?
Of the bicycle fatalities which I'm somewhat familiar, two were from
drunk drivers and one was from a heart attack.

"Investigators, however, have never provided a reasonable
explanation how (the cyclist), struck from behind, shares
responsibility for his own death..."

I'm also wondering if the statistics from other countries include or
exclude drunk drivers and heart attacks. Statistics without sources
are worthless.

Want to make the roads really safe for cyclists? Just execute drunk
drivers on the spot. Bicycle fatality statistics should drop rapidly.
However, I'm not sure it will affect the overall picture as some
cycling accident investigations seem to follow a "blame the victim"
mentality:

There are statistics that show the percent of drivers, both bicycle
and auto, who have imbibed.

http://www.iihs.org/iihs/topics/t/pe...facts/bicycles
Among bicyclists ages 16 and older who were killed in 2015, 23 percent
had blood alcohol concentrations (BACs) at or above 0.08 percent.

https://cityroom.blogs.nytimes.com/2...d-bike-deaths/
Some 21 percent of autopsies for New York City bicyclists who died
within three hours of their accidents detected alcohol in the body,
according to a Department of Health and Mental Hygiene study that
examined fatal bicycling accidents in New York City from 1996 to 2005.

http://www.latimes.com/business/auto...027-story.html
( referring to fatalities ) 28% of riders age 16 and older had blood
alcohol concentrations of .08% or higher, the level at which someone
is considered impaired.

I googled on "bicycle fatalities+cyclist who have high BAC" and there
were 1,050,000 hits.
