i don't think they ever believed the previous sensors were capable of "full autonomy". the reason they didn't throw in all these sensors sooner is that it would have been a premature optimization considering their lack of experience and also pretty expensive in terms of the hardware (which includes the GPUs necessary to make use of the sensors).
