My turn signal was on, and as GAXIBM detailed, Mazda states the system may not operate. It does not state that it cancels the system. The programming for each function seems to have been tested individually for each of the functions and the way they integrate with each other and driver inputs was not tested thoroughly enough. This issue with Mazda's software coding of different functions not being well tested for their integrated performance is not limited to the safety systems. It also rears its head in other areas, for example: https://mazdas247.com/forum/t/car-jiggles-after-30-sec-at-stoplight.123875951/If in that situation, with your foot on the accelerator and steering into the next lane, your signal should be on. Having the signal on cancels the lane departure warnings (as @GAXIBM mentioned), so maybe it also cancels the automatic emergency braking in that scenario too? I don't know for sure. But it would make sense for the system to use that info to determine what the driver's intent is, in addition to steering and acceleration input.
