I can't speak for the OP, but Autopilot definitely does NOT see NJ deer.
I've almost taken out one earlier this spring (had to brake and swerve behind it onto the shoulder), during the mating season. That was soon after I got the TM3, when I still had way too much trust in AP.
Not detecting wildlife is one of numerous AP limitations.
Adjust your expectations and behavior patterns accordingly.
Thanks for the confirmation. That has been my experience as well that Autopilot doesn't handle erratic deer.
