No one was driving Tesla before fiery crash that killed 2 passengers in Texas, authorities say

Two people were killed in the fiery crash of a Tesla and authorities say there was no one in the driver's seat, although it is not clear whether the car's driver-assist system was being used. A Harris County constable told television stations in Houston that there was a person in the front passenger seat and another in a rear passenger seat after the wreck in the Houston suburb of Spring.

Harris County Precinct 4 Constable Mark Herman said authorities are certain that no one was driving the car at the time of the crash. "They feel very confident just with the positioning of the bodies after the impact that there was no one driving that vehicle," Herman told CBS affiliate KHOU-TV.
