The key to Google's success has been that these cars aren't forced to
process an entire scene from scratch. Instead, their teams travel and
map each road that the car will travel. And these are not any old maps.
They are not even the rich, road-logic-filled maps of consumer-grade Google Maps.
They're probably best thought of as ultra-precise digitizations of the physical world, all the way down to tiny details like the position and height of every single curb. A normal digital map would show a road intersection; these maps would have a precision measured in inches.
