Jared Overton, an owner of a Tesla Model S, is digging for answers after an incident that took place on April 29, 2016, in Lindon, Utah.

Overton told media that he was running errands and had parked his Tesla behind a trailer near 400 North and 1030 West in Lindon. As he stepped out of his vehicle, the Tesla owner was approached by a worker at a nearby business who met him by the side of the road. The two then discussed features of his car.

They reportedly stood by the car for about 20 seconds to a minute and then walked inside the business building. Overton and the worker left the building 5 minutes later to discover that the Telsa had indeed, driven itself under the parked trailer in front, destroying the Tesla’s windshield.

Overton immediately reported the incident to Tesla, who responded with a letter that explained the collision was his fault.

According to KSL, the letter addressed to Overton by a regional service manager read:

“Tesla has reviewed the vehicle’s logs, which show that the incident occurred as a result of the driver not being properly attentive to the vehicle’s surroundings while using the Summon feature or maintaining responsibility for safely controlling the vehicle at all times.”

The letter further mentioned that the Summon feature, which enables self-parking, was initiated by the driver, and 3 seconds after Overton left his car and closed the door, the Summon feature started.

Overton rebutted these findings and claimed he put the vehicle in park. He also remarked that if the Summon feature had accidentally initiated, the car should have parked itself.

The Telsa driver told media that no company official spoke to him directly about his concerns regarding the crash, and that the company assumes that he sat there and watched the crash unfold.

Overton continued that the company’s letter dismissed the recount of two witnesses at the scene of the accident.

This driver’s concern isn’t about the money, as his windshield repair amounted to about $700. His greater concern is the safety of other drivers and pedestrians out on the road.

As seen in the video from NBC, Overton told reporters:

“Imagine if a child was right there — I guarantee that they would be responding to this a lot differently. I will not feel safe with my little boy playing in the garage or the driveway if there’s the potential for a rogue vehicle.”
