Adjusted and tested plenty this weekend. Drove in and out of the driveway approach at least two dozen times, with cars, trucks, bikes, and foot traffic.
I see your sensitivity is set to 8. Best results for tracking were at the default, 5. Set to 3 or less, no tracking. 8 or above, wacky tracking or none at all.
Also, a vertical intrusion box works the best for tracking, from my testing. One that captures the height of the object, not just crossing a line on the ground, like a 4 sided tripwire.
YMMV
