E340 Video Doorbell Vehicle Detection?

Vehicle detection works as expected but it’s also detecting them outside the activity zone I set to exclude anything within 5 ft of the sidewalk. I know it’s beta but I was hoping to be notified of vehicles pulling into the driveway, not just driving by. Any advice?

I get notified sometimes of a parked car if someone comes to my door.

I suspect the alerts are tied far more to the overall motion sensitivity level than set activity zones, which makes me wonder if setting zones actually does anything at all given I get alerts of people walking along the sidewalk, outside the zones if I bump up the sensitivity level. Ditto with vehicles driving by outside the zones.
