0:00 / 1:06

The National Highway Traffic Safety Administration announced an investigation into autonomous vehicle startup Comma.ai following five crashes linked to its aftermarket driver assistance devices. These incidents resulted in three deaths and eleven serious injuries, predominantly involving vehicles striking stationary or slow-moving traffic. Comma.ai utilizes open source software to provide features including steering, acceleration, and automatic braking, reporting over thirty thousand equipped vehicles. Regulators will evaluate system safeguards, performance, and operational status during the crashes. Previously, in two thousand sixteen, federal regulators and state officials challenged the company regarding safety proofs for proposed self-driving kits. The probe aligns with heightened regulatory scrutiny on advanced driver assistance systems nationwide following similar investigations into Ford and Tesla. The company maintains that its technology mandates continuous driver alertness and readiness to assume control immediately.
