Say it with me, "reasonable expectation of privacy". Do you have a reasonable expectation of privacy when driving your car on a public road, or when you crash that car on a public road? Of course you don't. And, it's not the video that's illegal here, it's the accompanying audio portion of the tape.
Everything you've described are scenarios that play out in public, which is not an ideal setting to have a reasonable expectation of privacy.
As for your "60 Minutes" question - 60 Minutes would not be able to surreptitiously record conversation in Maryland, and about 12 or so other states.
The most famous case in this regard is Food Lion v. ABC. I believe the case was about an incident in a Carolina grocery store, where ABC recorded some kind of malicious behavior in the butcher section of a Food Lion. This state had a two-party or all-party consent law, like Maryland. Food Lion sued damages suffered for ABC's violation of the relevant law. Food Lion won the case, but the jury only awarded a dollar or two in punitive damages because the conduct that was captured by the ABC news crew was so reprehensible, they weren't moved to award Food Lion any substantive damages.
