I suppose the current technology bit does restrict things massively. But I will say that there are a ton of options to optimized the current single occupant vehicle model. Self Driving can do a lot of things that increase the efficiency of roadways. Eg: If everyone's vehicle went to a fixed 10mph idle speed as soon as the light turned green we'd get far more vehicles through a light rather than cascading 1-2 second reaction times to the next vehicle's brake lights (and much more if the person is on their phone, which is increasingly common) . Eg2: Self driving cars could drive much closer to eachother, and actually pre-communicate intent to brake giving the effect of negative reaction time. (relative to humans)
