.... A lot of cameras have an IR filter to keep infrared from reaching the sensor. Since the focus point for IR is different than for visible light, getting a clear image is enhanced by blocking the out of focus IR,...

You are talking about a camera optimised for visible light. Of course that has filters cutting out extraneous light that it's not meant to respond to.

But why on earth should a sensor INTENDED to pick up IR have an IR filter? That makes no sense. I am pretty sure that the design engineers would have speciified technology wich was designed to do its job. And that its job was to detect obstacles around the car in varying lighting conditions - which includes pedestrians in a night-time street. That there was a failure there is obvious. But I don't think it was as simple as using a technology which was not designed for the task....
