    Eh, phantom braking is definitely a problem. It's gotten better, for sure, but I've definitely had times where there was nothing within 1/4 mile in front of me on the highway and suddenly it slammed the brakes. When I first got my Tesla in 2019, there was one specific overpass that I would go under during my commute that seemed to have a ~20% chance of triggering automatic emergency braking. I got into the habit of preparing to stomp the throttle which would override AEB. Luckily, a software update came out a few months in that seemed to fix that specific case. Now, I've done 1,300 mile road trips that didn't have a single phantom braking incident.

I've experienced this in a Subaru CrossTrek, several times while driving down back roads it started beeping at me "OBSTACLE DETECTED" and then slammed on the brakes when there was nothing in front of me.

  Back roads meaning dirt roads? Could it be the cameras mistaking dust for an obstacle?

    Nope, just regular old paved winding back roads.
