Abstract: Example passenger validation systems and methods are described. In one implementation, a method receives, at a vehicle, a transport request indicating a passenger and a pick-up location. The vehicle drives to the pick-up location and authenticates the passenger at the pick-up location. If the passenger is successfully authenticated, the method unlocks the vehicle doors to allow access to the vehicle, determines a number of people entering the vehicle, and confirms that the number of people entering the vehicle matches a number of passengers associated with the transport request.

Abstract: The present invention extends to methods, systems, and computer program products for a heads up display for observing vehicle perception activity. As a vehicle is operating, an occupant can see objects outside of the vehicle through the windshield. Vehicle sensors also sense the objects outside the vehicle. A vehicle projection system can project a heads up display for the sensed objects onto the windshield. The heads up display can be aligned with a driver's point of view so that graphical elements projected on a windshield overlap with their corresponding objects as seen through the windshield. As such, a driver (e.g., a test engineer) is able to view algorithm output (e.g., perception algorithm output) without having to look away from the road while driving. Accordingly, testing driver assist and autonomous driving features is both safer and more efficient. The heads up display can also be used as a driver assist.

Abstract: Example accident attenuation systems and methods are described. In one implementation, a method determines a speed of a second vehicle approaching from behind a first vehicle and determines a distance between the first and second vehicles. The method also determines whether the second vehicle can stop before colliding with the first vehicle. If the second vehicle cannot stop before colliding with the first vehicle, the method takes action to attenuate the potential collision by applying full brake force, tightening seat belts, and/or turning the front wheels of the first vehicle to direct the first vehicle away from oncoming traffic.
