Well, object labels and velocities is not a world model. You can say that they are the attributes necessary to build one, but just a bunch of values is not a model.
Current tech builds a (statistical) model of some aspects of the world that an agent must navigate- aspects that pertain to entity types, trajectories, velocities and so on.
But other bits are missing and they are important ones- for example, what is a human doing on top of a bicycle moving at the same speed as him or her? What is the relation between a driver and a car? And so on. We can still not represent stuff like that with any accuracy to speak of.
In short, what's missing for the most part is a representation of the relations between entities in the world- even where we can accurately represent the entities themselves, or their characteristics.
Sure it is. Whether it's an adequate model for some particular purpose is another question. But no model includes everything.
Objects and velocities would be a good start. I don't know enough about the present state of the technology to know whether we even have that. But from some of these accidents we're seeing, it seems like we don't.
I would agree that a better model would attempt to infer intentions: what is that driver/cyclist/pedestrian likely to do next, based on what they're doing now?
