According to preliminary investigations, police are "almost 99.9 per cent sure" that no one was behind the wheel, the spokesman said, as cited by the Wall Street Journal.
The paper reported that authorities are still investigating whether the vehicle's driver-assistance programme was turned on.
Autopilot function
Tesla's official advice states that the Autopilot function on its cars reduces the driver's workload, but that it should be used with a fully attentive driver who has their hands on the wheel and is prepared to take over.
Although the functions are becoming more powerful over time, they do not currently make a vehicle autonomous.
