MINNEAPOLIS -- A suburban Twin Cities man is blaming the autopilot feature of his luxury electric car for a crash that sent him and four passengers into a central Minnesota marsh.

David Clark, of Eden Prairie, says he was driving his Tesla near Willmar Saturday when the car suddenly accelerated and overturned in the marsh.

The Star Tribune reports Kandiyohi County sheriff's deputies arrived to find the Tesla on its roof. The sheriff's office says Clark and his four passengers suffered minor injuries, CBS Minnesota reports.
