BACKGROUND

Field

Various embodiments disclosed herein relate to vehicles. Certain embodiments relate to self-driving vehicles.

Description of Related Art

Vehicles typically require a driver. These vehicles often can only perform actions when directly steered by the driver. However, self-driving vehicles are not reliant upon drivers and can perform actions based upon particular events. Self-driving vehicles can dramatically increase travel safety and convenience. As a result, there is a need for systems and methods that enable self-driving vehicles to perform actions based upon particular events.

SUMMARY

Self-driving vehicles will save tens of thousands of lives per year. The majority of vehicle-related deaths are caused by driver error. Tests have shown that self-driving vehicles nearly eliminate self-inflicted accidents (although they are not immune to accidents caused by human drivers of other vehicles). Self-driving vehicles have unlimited attention spans and can process complex sensor data nearly instantaneously. The ability of self-driving vehicles to save lives is so impressive that society has a moral imperative to develop self-driving technology such that it can be widely adopted.

Self-driving vehicles also have the ability to dramatically save time and improve convenience in roadway travel. Specifically, self-driving vehicles have unlimited potential to learn and predict human behavior and perform actions accordingly. Some embodiments enable a self-driving vehicle to monitor human activity and predict when and where the human will be located and whether the human needs a ride from the self-driving vehicle. Self-driving vehicles will be able to perform such tasks with incredible efficacy and accuracy that will allow self-driving vehicles to proliferate at a much faster rate than would otherwise be the case.
