In Chapter 9, Singer quotes Susan P Baker, who tells us her approach to accident prevention: make the world safe for drunks.
“The bottom line is if you make this world safe for drunks, you make it safe for everybody. If you focus on making the world safe for the average, reasonably smart, sober person, then the drunks, the sleepyheads, the guy who is worried about his child’s operation and trying to get home in time for it, it is not going to be safe for them.”
