System redundancy in safety-critical systems exists for a reason. Either their engineering team refused to see this or they were unable to make Product/Management/Regulatory people see it.
AEB is quite finicky and needs quite a fair bit of calibration and mechanical alignment, still like the article says can suffer from false positives.
But although LIDAR is still prohibitively expensive it is possible to design ADAS that can integrate stereo camera, RADAR and long range sonar, that would at least give you three sources of data for some margin.

The spectrum used for AEB in most transceivers is 76 GHz to 81 GHz (so between about 3.9 and 3.7 mm) some older implementations also worked at 24GHz i think.
