Road rage is as old as the automobile, if not older.

Growing up in the 70's and 80's, I remember my dad shout obscenities at other drivers (mostly PUVs) for cutting him or stopping in the middle of the road to pick-up or drop-off passengers. Thank God there were no cameras back then. He's significantly mellowed-down now in his late-70's.

All that to say, it's because of the abundance of phone cameras, dashcams, CCTV, etc., together with platforms on social media, that we're finding out more about these things.
