The reality is. You have to ride as if you are invisible to 50% of car drivers and the other 50% are trying to kill you!
Regardless of if they are on the phone, in a vehicle with poor visibility, left hand drive, if they are lost, distracted, foreign, inexperienced, old, disabled, tired, impaired through drink or drugs, unfamiliar with the area... whatever. It is your vigilance that will keep you alive.
You can film them all day and get angry but you'll just annoy yourself and everyone else on the forum.
I drive 50-70,000 miles a year. I've seen it all and made a few mistakes in my time. Oh well! :-)
