The article made it seem Nissan's engineers couldn't fathom not using car-to-car communication to enable autonomous driving. I found it hard to believe anyone act that way. Relying on car-to-car communication would create an enormous chicken and egg problem. I suspect the author overstated the level of disbelief here.
