Abstract: A method, system and product for implementing user-based ethical decision making in autonomous vehicles. The system includes an ethical investigator that presents an ethical questioner to an entity and collects the entity's responses. An ethical synthesizer synthesizes an ethical preference of the entity based on the collected responses. An ethical determinator selects an action from a plurality of potential actions based on an ethical preference of a controlling entity of a self-driving vehicle at a time the selection is made. The system is configured to cause the self-driving vehicle to perform the action selected by said ethical determinator automatically and without relying on user input.

Abstract: A method, system and product for user-based ethical decision making by a self-driving vehicle. The method comprises determining an ethical preference for the self-driving vehicle based on an ethical preference of a controlling entity that is controlling over the self-driving vehicle. The ethical preference of the controlling entity is obtained based on responses of the controlling entity to an ethical questioner. The method further comprises selecting a selected outcome between two potential alternative outcomes. The selection is performed based on the ethical preference for the self-driving vehicle, and causing the self-driving vehicle to perform the selected action, whereby causing the selected outcome.

Abstract: System, method and product for vehicle navigation. A method comprising obtaining a location of a vehicle and obtaining a data about the passenger in the vehicle. Based on the data, a constraint on a driving route of the vehicle is determined. The constraint is characterized in extending the driving route so as to extend a driving time to the destination to be longer than a minimal driving time from the location to the destination. A driving plan is generated based on the constraint, wherein the driving plan defining a route from the location to the destination, whereby the vehicle can be driven according to the driving plan.

Abstract: A method, system for encoding or decoding information in physical properties of an object. A tangible product comprises a three dimensional tangible object having modified physical properties; and wherein the modified physical properties are a modification of physical properties, wherein the modification encodes information. A method comprising: obtaining a representation of a three dimensional object having physical properties; obtaining information to encode; determining modified physical properties by modifying the physical properties to encode within the modified physical properties the information; and producing a tangible product, wherein the tangible product is the three dimensional object having the modified physical properties.
