Evidence-based policy


Posted by Matski on October 11th, 2006

Omigod.  A state actually making public policy based on evidence.

From Michigan:

The state says it’s increasing speed limits to make freeways safer through realistic speed limits that encourage more uniform traffic flow.

One of my public policy bugbears is the insistence on enforcement of too-low speed limits.  In WA state, for example, we’re subject to ads noting “speed is a factor in 1/3 of accident-related deaths.”  Yes, true — if you drive faster, you’re more likely to die in an accident.  BUT — a leading factor after alcohol in CAUSING accidents is speed differential.  That is to say, you’re more likely to BE in an accident if you’re driving, say, 65 (the limit in most states), while granny insists on driving 40 (the minimum in many places).  If you drove 70 while granny drove 55, the DIFFERENTIAL would be 10 mph less, and you’d be less likely to crash in the first place, and therefore your risk of death is reduced.

But fearmongering state police such as those we’ve got here in the Evergreen State stick strictly to the CW, wrong though it is.  Tragic.
