BC raised the posted speed limit and guess what?

The posted speed used to be 80 KMPH on one BC highway and the 85th percentile of drivers were clocked at 98 KMPH.   A senior engineering administrator in the BC Transportation Ministry told me what happened when the posted speed was raised to 90 KMPH in 2014.  The 85th percentile dropped to 93 KMPH.
Reposting the Coquihalla in 20-14

My takeaway:  When you place unreasonable limits on choice, people make their own rules.  When you place reasonable limits, they will often accommodate themselves to the limits.  In this case, raising the posted speed appears to have made the road safer.

Example where force of law is invoked
for an unreasonable limit.
Choice is crushed because we depend
on others to make our bulbs.
