It is also very important to consider the effect on other drivers. A self driving car might calculate it can squeeze through a gap in oncoming traffic but doing so probably will cause human drivers of those cars to slam the breaks and create a large crash. So unless they’re driving on a road where only self driving is allowed they’ll probably need to be much more conservative than they can be. Also thinking about it, the first roads to become robot-only driven will probably be inner city streets where pedestrians abound, so no aggressive driving there either.
