There aren't many people left who have the passion you have for demanding the MTA "do the right thing". Likewise, I tend to agree with most of your points and suggestions (with occasional exception), but this from the perspective of a bus driver.
The MTA as a whole cares little about buses, and would rather not have to deal with buses at all. The MTA has always, and continues to view the "Department of Buses" a liability.
You cannot reason with the people who make decisions for this out-of-control, autonomous bureaucracy. For one, they do not care what anyone outside upper-management thinks, says, does or suggests. There is a pipeline of arrogance that is perpetuated in even the smallest locations throughout the system. Along with arrogance is intimidation, threats, harassment and other factors that further pollute the system, the employees, the general riding public and how things work (or don't work) as a whole.
By design, MTA policy is written to (a) hold the MTA harmless, and (b) cause friction between their employees and the riding public. Policy is not written for the betterment of public transportation. It's written to minimize potential liability, and/or place as much liability elsewhere, be it with the riding public or the employees. Sometimes both.
If you want to connect with the MTA in any "meaningful" way, find ways to enlighten them as to how your suggestions lessen potential liability. You might see a more proactive response. "Might", that is.
This, of course, from my perspective in Surface.
