Regarding the issue of mesirah:
Does it make a difference in determining whether it is mesirah, if all factors being the same, the only difference is in once case the homeowner calls a private tower to tow, or in another case the homeowner calls a government tower to tow?
Is it mesirah to call the local precinct to have the vehicle ticketed (for blocking your driveway)?
Is it mesirah to report that a curb-cut (in front of the homeowners driveway) is illegal?
If a homeowner is responsible for fixing cracks (wear and tear) on the public sidewalk in front of his house, is it mesirah to report it to the city, if the city’s only action would be to enforce the homeowners obligations, with no other penalty (assuming the homeowner complied upon demand)?
