why would a tv show using gopro's to film a show have anything to do with dashcams? i dont think anyone here is suggesting you can't film stuff with gopros, but if you want to film for the purpose of protecting yourself in the event of an accident of course a dash cam is the preferred choice here on a dash cam site. the time you forget to turn your gopro on or are too lazy because you are just running to the store real quick could be the time you get in an accident and really needed the camera rolling. but of course a $400 gopro designed for capturing action with the best quality video possible in a handheld size is gonna have higher quality video.
I use a few gopro clones (sjcam 4000, blackview action cam) for filming special footage for example two weekends ago:
But i have to mount those each time, they don't start recording until I hit the record button, and they don't loop (well these CAN loop and be used like dashcams, more so than a gopro even, but I don't put them in that setting). they record videos for entertainment not for insurance reasons. I use those cams for their purpose, capturing action. but I would never use them as a permanent dash cam solution, nor would I use a gopro because they are inconvenient to use every single day each drive I take.
but hey, if you have no problem using a gopro then go for it. even if everyone here says its a bad idea, if it works for you then it works for you. Basically you are giving up what most here consider fundamental features of a dashcam for the best quality footage you can get and thats your prerogative. Its sort of like how I will
give up video quality for automatic parking mode. we all got our needs.
