The National Transportation Safety Board (NTSB) has launched an investigation into a tragic crash in Texas, where Tesla driver Michael Butler allegedly hit and killed 76-year-old Martha Avila at high speed while using Autopilot.

Butler claims he was relying on the system but Tesla’s data suggests otherwise. The company says his foot was pressed to the floor, overriding Autopilot and pushing his car to 73mph before the fatal impact.

The case raises serious questions about the reliability of autonomous driving technology and who should be held accountable when things go wrong. As the NTSB and NHTSA delve deeper, the stakes get higher for both drivers and manufacturers.

Meanwhile, Martha Avila’s family has filed a lawsuit against Butler and Tesla, accusing them of negligence. The outcome could set important precedents in an age of increasingly self-driving cars.
