Yes, with 100% consistency on eastbound 470. Don't remember the exact exit, but it's somewhere between Broadway and I25. Happens every time.
It's very weird behavior, but it isn't like the other phantom braking events I experience. Rather than a false emergency braking event, the car simply chooses the wrong speed limit, Seems like bad mapping data or the cameras spot a "45mph exit" speed limit sign and interpret it incorrectly.
Either way, it's frustrating, and could be dangerous. There needs to be a reporting mechanism for weird/wrong autopilot behaviors.
