Traffic in San Miguel

I have been walking twice a day for the time we have been here. This is probably only the second time in fifty years that I have not driven for more than a couple of days.   There are no stop signs in downtown and precious few in the outskirts.   The average speed on the streets is probably less than 20 miles per hour.  (This is a place with narrow cobblestone streets and lots of topes- little traffic mounds).  

Amazingly what I have found is that with few exceptions the drivers are courteous.  They yield to pedestrians almost unfailingly.  That is certainly not true in other parts of Mexico or in the US.
