A human driver is required to drive vehicles. However, human drivers occasionally face some difficulties: we have to park our car far from where we are going; poor weather conditions make it difficult to get to the car, or; it can be difficult to get to the car in a crowded parking lot.
Over 550,000 Tesla Smart Summon uses in first few days!— Elon Musk (@elonmusk) October 2, 2019
This feature allows the vehicle to navigate the parking lot and drive up to the owner or to a destination of their choice while their vehicle is within their line of sight. It’s the perfect feature to use if you have an overflowing shopping cart, are dealing with a fussy child, or simply don’t want to walk to your car through the rain.
The feature is described as "a processor coupled to memory is configured to receive an identification of a geographical location associated with a target specified by a user remote from a vehicle. A machine learning model is utilized to generate a representation of at least a portion of an environment surrounding the vehicle using sensor data from one or more sensors of the vehicle. At least a portion of a path to a target location corresponding to the received geographical location is calculated using the generated representation of the at least portion of the environment surrounding the vehicle. At least one command is provided to automatically navigate the vehicle based on the determined path and updated sensor data from at least a portion of the one or more sensors of the vehicle."

Thanks to a group of inventors led by Musk, Smart Summon makes life easier for Tesla owners. He is passionate about Tesla's products and strives to improve and develop them. Musk himself created and improved some functions in Tesla cars because he is not just a leader, but an inventor who fully understands how vehicles work. It is Musk that is Tesla's secret sauce.
