A federal court in Miami began considering Monday whether Elon Musk's car company should share blame for the death of a stargazing university student after a runaway Tesla sent her flying 75 feet through the air and severely injured her boyfriend.

The confidential settlement was disclosed ahead of a separate trial related to another fatal crash involving its driver-assistance system.

A critical voice took the stand Wednesday in the first-ever federal jury trial involving Tesla’s Autopilot system: a safety expert who says the technology is defective and promoted in ways that encourage misuse.
