Technologies for reducing vehicle door collisions include an in-vehicle compute device configured to determine a proximity between a door of a vehicle and a structure while the door is being opened and activate a door collision avoidance system of the vehicle to slow or restrict the opening of the door in response to a determination that the proximity of the door to the structure is within a proximity threshold. The door collision avoidance system may include one or more electro-magnets, one or more actuators, and/or one or more electro-active polymer devices. The in-vehicle compute device may also control the operation of the door based on a context of the vehicle.
