原推:Developing a robotaxi system that can interpret and navigate intersections de novo is a monstrously difficult task
But it is the only scalable (and safe) way to solve autonomous driving https://t.co/JSkCFG3SZX
Each intersection annotation creates an ongoing maintenance cost since intersection composition decays (road construction, vegetation occluding signs, etc)
And # of intersections is an exponential of the # of road segments.
So costs ~4x as road-segments serviced ~2x.
