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.
