Along the "tight budget" line, it certainly doesn't help local budgets having to buy the extra diesel fuel when these beasts have to run for a half-hour or better just to burn the soot out of the particulate filter.

And at least with the Class 8 post-2007 rigs we built at Freightliner, there's going to come a point where after so many cancelled cycles, the ECM is going to force you to keep the truck idle at the side of the road until it does complete a full regen cycle.

I'd say the gent's overall argument does have some merit - just as it would be sheer lunacy to force an M-1 tank crew in a combat zone to have to worry about a requirement such as this, the FD/EMS units already have more than enough on their plates trying to respond to calls and save lives, not to mention often having to deal with situations that threaten their own lives, than to also have to deal with such bureaucratic nonsense.
