Following the Model S crash of a car in Ukraine, Tesla has updated their "Summon" mode, which is a self-parking feature, in order to assist drivers from avoiding mistakes when these are on.

The feature of the Tesla Model X and Model S instructs one's vehicle to autonomously park or come to the person. The travel direction of the vehicle will then be confirmed by the owner once it is correct. The update comes after a Utah user's Model S vehicle rolled into the back of a trailer because it was in the "Summon" mode, Auto Blog reported.

The owner of the vehicle claimed that he stood in front of the vehicle for a minute but the vehicle crashed on its own after he left it as he went inside a store. However, Tesla said that in the logs, it showed that the driver initiated the Summon mode and received several warnings and messages before the vehicle started moving. Accordingly, the crash came seconds after the man exited the driver-side door.

The latest update will be preventing user error by asking for confirmation about whether the car will be moving forward or reverse before it does any action, Tech Radar reported. Tesla said that the self-parking feature of the Model S and Model X vehicles may not be able to detect certain obstacles such as bikes or those that are lower than the fascia and those that are hanging from the ceiling.

Value Walk reported that Summon was first released last January and can be activated in two ways. The first way it via the phone app while the other is via the gear selector from inside of the car.

Also in the past, Tesla issued a "dead-man's switch" for the Summon feature that requires users to continuously press the key for or their smartphone. If a person releases his or her finger, the car will immediately stop.

Tesla said in a statement that they are always making improvements to the features in their vehicles.
