This article seems to have tunnel vision on speed as the primary cause -- "Speed is what kills", it claims, and links to another page on their same blog that says: > Speeding — defined as traveling too fast for conditions or in excess of the posted speed limits — contributes to nearly one-third of all roadway fatalities. This proportion has remained largely unchanged for decades. They neglect to mention that, in America, alcohol contributes to about one-third of all roadway fatalities, too. In Norway, it's much rarer, due to stricter limits (.02 BAC!) and harsher penalties. Big complex problems often have multiple contributing factors. Personally, I'd go after alcohol first. IME, nearly everyone on the road speeds, and apparently nearly everyone can do it safely. It's hard to argue that drunk driving can ever be done safely. The best "traffic calming" street designs in the world won't keep your city center safe from drunks.
