This is interesting because ANCAP stated the following

>The autonomous emergency braking (AEB) system is capable of detecting and reacting to pedestrians and cyclists. The AEB system showed GOOD performance in pedestrian test scenarios in both daylight and low light, with collisions avoided or mitigated in most scenarios including in turning scenarios and some reverse (AEB Backover). In cyclist test scenarios, the AEB system offered GOOD performance with maximum points scored.

It wouldn't be difficult for Tesla to just bump up the sensitivity for the test - ensuring that it acts extra cautiously for the test, and then have it lower in real world scenarios where they're worried false positives would make it unusable.
