I wonder why Amazon didn't reveal this during their yearly product announcements in September.
Anyway, the Ring Car Cam is ready for pre-order. -->

It appears to be what Ring door bell does. That is, it records when it detects motion. Since it's hooked up to the ODB II port it is powered all the time, regardless of whether your car is running or not. It does not appear to be a dashcam as far as I can tell. The product description does not say anything about recording accidents or other events while driving unless you ask it to record. And you when you ask it to record, it only records for the next 20 minutes. So in a way, this is exactly like the Ring doorbell. It does not record continuously.
