Car Vandalized 4 Times But Never Caught On Ring Doorbell 3

I have had 4 vandalism incidents of my car parked in front of my house: the side window was broken 3 times, and the rear license plate was stolen. I need to know why Ring Doorbell 3 did not catch any of them on video. Motion sensitivity is set to maximum. Smart alerts are set record and send alerts for people (not other motions so I don't record every car that drives by). Motion zone includes my car and the areas front, back and above it. Motion frequency is set to frequently. Ring alerts, motion detection, and motion alerts are all on. Snapshot capture is set for every hour, but I often have nothing showing all night long. And I keep the battery charged. What have I missed?
