Oh, Elmo

Mechnical turks everywhere you are told about "machine learning."

Tesla's self-driving cars seem like a marvel of machine learning.

But in reality, the company relies on a small army of human "data annotators" who continuously improve how the cars drive by reviewing camera footage from thousands of Tesla drivers and teaching the vehicle how to behave like a human driver, like deciding when it's appropriate to use a blinker or identifying a construction cone.

Business Insider has learned that those annotators focus their efforts on two high-profile categories of drivers: Tesla CEO Elon Musk and a select set of "VIP" drivers.

They're dedicated to improving the commutes of their special customers. Amazing.
