Irresponsibility — by carmaker Tesla and by a Tesla driver — contributed to a deadly crash in California in 2018, federal investigators say.

The driver appears to have been playing a game on a smartphone immediately before his semi-autonomous 2017 Model X accelerated into a concrete barrier. Distracted by his phone, he did not intervene to steer his car back toward safety and was killed in the fiery wreck.

But Tesla should have anticipated that drivers would misuse its "autopilot" feature like this and should build in more safeguards to prevent deadly crashes.
