Toyota pre-collision system (pcs) on 2016 rav4. i never get any kind of warning, even when cars cut me off at highway speeds, i approach a car from behind at speed (i cannot get too risky here), etc. other pcs systems on friends cars (non toyota) have some warnings, even false ones a bit. i asked my dealer to check it was working, they had no procedures to test it other than obdii for sensors out. seems like the promised and iihs tests indicated that this pcs system worked to stop the car. on line searches i cannot find anyone who has seen their system working or alarms. the toyota video indicates warnings seem to occur at 7-10 car lengths - i have been cut off on highway at less than one car length with no warnings.
