Why don't more people pull over to salute flag raising and lowering?

I wouldn't consider it an extra step CH (MAJ) William Beaver, because it's required.
According to Appendix C of Army Regulation 600-25, "Salutes, Honors and Visits of Courtesies," military personnel in uniform should face the flag and render hand salute during reveille, and during retreat they should face the flag and stand at attention. Military personnel and civilians in civilian dress should remove headgear, face the flag and stand at attention with their right hands over their hearts during reveille, and during retreat, they should face the flag and stand at attention.

In addition, Appendix C further details specific other instances like indoors and civilian attire.

Leadership at all levels down the CoC should be policing this -- deals with discipline, respect, and military values at their core.

Complete and utter loss of respect as well as a complete lack of any gratitude for those that came before.... I feel that there are to many children who needed a way out or a benefit for doing what they do as apposed to doing it for the posterity of this country and its people...the same with wearing the uniform incorrectly I strongly believe that any and all "acts of indiscipline" truly are a smite to our heroic predecessors period.... From the cover tipped back to not rendering honors.
