Help me, please, to understand why I would need or want a dash cam.
Will you ever need it? Probably not. If you do need it and don't have it. Well, your screwed.
I install them as insurance . i.e. if I'm ever involved in an accident or incident, it can provide documentation .
My nephew was involved in an accident. The driver that ran the red light claimed my Nephew ran the red light. There were no other witnesses, His word against my nephews. Guess what happened after the cop seen the video.. :-)
