A driver in a Tesla vehicle that was allegedly in driver-assist mode crashed into a Texas house Friday night, killing a woman who was inside the home, investigators said.

Michael Butler was traveling in his Tesla Model 3 around 8 p.m. local time in Katy, Texas, and was operating the vehicle “with an automated driving assistance system,” the Harris County Sheriff’s office said in a statement.

Butler allegedly failed to drive in a single lane, left the roadway and struck the residence, according to the sheriff’s office.
