Police say they are investigating.

The driver of a Tesla sedan died in a fiery collision with a tractor in Elk Grove early Wednesday morning, authorities said.

The crash happened at about 5:38 a.m. on eastbound Kammerer Road in southern Elk Grove. The California Highway Patrol said the grey four-door sedan hit the back of the tractor, which was hauling grapes on Kammerer Road just east of Lent Road in southern Elk Grove.

This is almost identical to the first Tesla driverless fatal crash in 2016, so basically nothing has improved.
