AI Summary

The National Highway Traffic Safety Administration has launched a formal investigation into comma.ai’s aftermarket driver‑assistance system after five crashes in which vehicles equipped with openpilot struck stopped or slow‑moving cars in the same lane. Two of those incidents resulted in three fatalities. The probe encompasses roughly 30,000 units of the comma three, comma 3X, and comma four devices. This investigation marks the most significant regulatory challenge for George Hotz’s startup since NHTSA forced the cancellation of its initial product in 2016.
