The NHTSA has expanded its investigation into Tesla's Autopilot system focusing on driver attention even after a recall fix.

Concerns have escalated following a recent fatal crash involving a Tesla on Autopilot, questioning the recall's effectiveness.

The agency is assessing whether Tesla's Autopilot is being used as intended and is considering imposing further penalties and corrective actions.

Despite the ongoing safety concerns, Tesla CEO Elon Musk continues to advocate for the capability of 'Full Self Driving'.

Safety experts and advocates maintain a skeptical stance on the technology's readiness and reliability.
