Analyzing Autosteer Data (Or Lack Thereof)

Elliot Williams has an interesting analysis of the NHTSA report on Tesla’s Autosteer capabilities:

But the NHTSA report went a step further. Based on the data that Tesla provided them, they noted that since the addition of Autosteer to Tesla’s confusingly named “Autopilot” suite of functions, the rate of crashes severe enough to deploy airbags declined by 40%. That’s a fantastic result.

Because it was so spectacular, a private company with a history of investigating automotive safety wanted to have a look at the data. The NHTSA refused because Tesla claimed that the data was a trade secret, so Quality Control Systems (QCS) filed a Freedom of Information Act lawsuit to get the data on which the report was based. Nearly two years later, QCS eventually won.

Looking into the data, QCS concluded that crashes may have actually increased by as much as 60% on the addition of Autosteer, or maybe not at all. 

This is a great exercise in statistical analysis and the problem of garbage in, garbage out.

We could manipulate those numbers in various ways to estimate total, unique […]
