Open strollers on Buses.
B35, VG8, and the like have already expressed their feelings and I as a bus driver share that (although I work on the oppo side of the Hudson).
Trainmaster hit it right on the head too. SAFETY, SAFETY, SAFETY. God forbid that op has to slam brakes and that stroller is not secured (what I mean is strapped down like we do the wheelchairs, but that's just not gonna happen). Another Armchair Quarterback with a misguided dream of contributing to society.
To quote my Drill Sergeant from Basic Training:
"Not only no, but hell no"
