I'm gonna take a page out of
@Panzer Platform book and say death to all hotspots haha
Just adds another layer of complexity to the setup, another internet subscription you have to pay for etc. To add to the subscription cost that the dashcam manufacturer will charge, because where are profit margins to be made except services (once they're all doing it)?
Only upside doing wifi hotspot I can think of is that heat generated by the dashcam will be less, compared to LTE but apart from that I'm not feeling it
