11 more people killed in crashes involving automated-tech vehicles

Eleven people were killed in U.S. crashes involving vehicles that were using automated driving systems during a four-month period earlier this year, according to newly released government data, part of an alarming pattern of incidents linked to the technology.

Ten of the deaths involved vehicles made by Tesla, though it is unclear from the National Highway Traffic Safety Administration's data whether the technology itself was at fault or whether driver error might have been responsible.

The 11th death involved a Ford pickup. The automaker said it has to report fatal crashes to the government quickly, but it later determined that the truck was not equipped with its partially automated driving system.
