Yes, if you have it set to identify both it will likely see both the car and the person.
The Ai looks at every image as though it's never seen an image from this camera. So it doesn't get use to your car parked in the driveway and ignore it. It could be trained to do that, but that is beyond me and likely would be harder to program unless the software becomes fully open source.
All that said if you only have it set to people and cars and the scenario you set up happened, but with a cat setting off the motion trigger in
Blue Iris, the Ai will still identify the car parked there. It will also try to identify the cat as a cat, but "ignore" the cat, not triggering past the Ai Tool based on the cat not being selected as a trigger.
