Yes, but what if the drone followed a car they __believe__ is law enforcement (where in reality it is not)?

The US doesn't have any general restrictions against filming in public.

Court rulings citing the amendments above were made to affirm that law enforcement are not an exception to the general rule that filming is allowed.

US doesn't have an expectation of privacy in public spaces. This allows for filming of anyone/anything in a public space. Following a specific individual or vehicle in public doesn't make a difference.

Simply filming in public is not a nuisance and should not be illegal.

There’s no expectation of privacy in a public place which includes public roads.
