I don't think you're seeing the future trajectory. Autonomous cars and trucks will be able to do their thing with a much smaller margin for error - because they don't make errors. So for example instead of two seconds distance to the car in front of you it will be 0.1 second. The vast majority of humans would have an accident as soon as they got on the road.
We need that increase volume and reduced accident count in order to grow without having to build more roads.
