Michael, et al.

I suppose metrication of highway signs would serve as good metric system 
training and education, but I need to stop and think to what extent it really 
contributes to  true transition to the SI as the standard of measurement for 
the United States, and I don’t think it does.

What form was H transition supposed to take? Dual speed limits prior to 
changing to metric only? What about metric education for the motor vehicle 
operators? What about odometers? And if odometers are switchable, how does the 
public relate to that, and how do their auto service mechanics deal with 
service intervals? How do we prevent service intervals fron becoming unevenly 
applied in kilometers and miles? How can we hope to change over to metric-only 
speed limit signs if metrication of signage is not administered hand in hand 
with changes to motor vehicle operation law, a/k/a the rules of the road?  

I very much want to see America go metric, but it isn’t a change that we can 
accomplish only outwardly. It is a systemic change. As measuring Americans, our 
roots are going to Have to grasp a new soil. I think the first step in U.S. 
metrication is metric-system education for every man, woman, and child in the 
United States.
