Every day it seems there’s now news of another Tesla crash with speculation surrounding Autopilot. The latest reported crash is now involving a Model X in Whitehall, Montana. This incident–like the first two–is being investigated by Tesla.

According to a post on owner’s website Tesla Motors Club the driver was driving on a two-lane road at night with Autopilot engaged at 60 mph. The Model X allegedly did not “see” a wooden guardrail and hit it, which completely destroyed the vehicle. Both passengers walked away from the incident without major injuries.

This news serves as a follow-up to two other accidents that allegedly involve Tesla’s beta Autopilot mode. The first occurred on May 7th in Florida, killing the driver. The second incident involved a Model X in Pennsylvania. However, the Model X driver has since been cited for careless driving and was not seriously injured.
