Is speed enforcement obsolete?

Editor,

I recently read that studies of traffic speeds on streets with 20 mph limits indicate people are traveling between 20 mph and 29 mph.

The report paraphrasing, postulates the speed should possibly be raised to 25 mph to better accommodate the prevailing speeds recorded. When that happens and speeds increase from 25 mph to 29 mph will we then raise the limits again?

Speed limits on Interstate 70 were 75 mph, yet most vehicles including semi trucks passed drivers doing 75 mph as though they were standing still. Now the speed limit is 80 mph and the traffic is still outpacing lawful drivers.

When did enforcement become obsolete?

Just curious.
