A Tesla driver caused a deadly crash and blamed the car, but Tesla's data pinned it on him — bad for the driver, good for Tesla.

• A man drove a Tesla into a house at high speed, killing an older woman inside.
• He claimed the car was at fault, but Tesla's sensor data showed he pressed the accelerator to 100% himself.
• The data showed he overrode the car's safety features, so it was not self-driving gone wrong.
• Elon Musk and a Tesla VP handed the telemetry to authorities, which helped get the driver charged.
• The case shows Tesla's built-in tracking can clear the company and expose the driver.

Outlook: The driver faces vehicular manslaughter charges, and Tesla's data will likely be central to the case.
