If all cars are autonomous it is more efficient to have two cards approaching at the same time negotiate a speed at which they can safely pass through the intersection without stopping or colliding. Stopping would be a thing reserved for when you get to your destination or a pedestrian gets in the way. It's more efficient that way. The energy needed to accelerate is less than the energy needed to maintain speed. Which of course bring sup the idea of hacking the negotiation so that you always have the favorable outcome. The same way some people try to hack the sensors that turn lights green for emergency vehicles.
