I don't feel it's the beginning of needing a dash cam. Years ago after viewing a video on this site, I immediately went to Tuckom and bought a dash cam. What the video showed was a younger Thai lady barely slowdown at a crossroad with a major boulevard. Subsequently she was struck by another pickup in from of the one with the dash cam and then once more by the dash cam pick up. The young MC driver died and the pick up driver felt he would have easily been charged had he not had his exculpatory evidence.
I think this sad even happened in KhonKaen but my memory may have failed me.
Having a dash cam was likely a good idea since the day they became available.
