If the data doesn't have the details required to build accurate models, then the data is just costing Tesla money. Since Tesla's are just cameras only, with telemetry, they can replay scenarios with existing roads, but what happens when someone cones off half of the road?

I imagine they have a way to replay incidents from their cars in a simulation and even if it's not super accurate, they could likely look at camera data and rebuild a similar situation (Sim or real life to identify and test the edge case)

I work at another autonomous car company (as a security engineer not ML related work) and I know we have a Lot of simulated situations that we run the ML against and add more from situations collected from actual driving.
