You can't bomb an apartment without also hitting the neighbors. And while we know the US has the the technology to hit a car driver without (physically) hurting the passenger, we also know that this is not the type of technology deployed regularly.
I don't think a drone operator would be naive enough to believe that they are killing exclusively military targets and no one else.
