The vehicles are intended to be very predictable for other drivers. I don't consider that to be synonymous with encoding intent into subtle microbehaviors. Instead it means straightforward behaviors like turn signals, appropriate speeds, avoiding last minute lane changes, etc.

One of the big ways people predict what cars are going to do is by reading intent through both macro- and micro-behaviors. Reading motion intent through subtle motion indicators is not just part of driving; it's something that happens all the time, and not just for humans. Automated vehicles are entering into an environment where that's the case, and that will not change.
