A remote-assist system programmed for vehicle parking assist or other remote vehicle operation features includes a selective ultrasonic beamforming Amplitude Modulated (AM) system configured and/or programmed to transmit audible alerts to a primary user via ultrasonic beamforming AM. The system localizes a mobile device that is being used by the primary user to initiate the system. The system localizes the primary user, and others in the vicinity, and determines others that may be associated with the vehicle and primary user. The system defines and reshapes a target zone to include only those associated with the primary user and the vehicle. The system electronically or mechanically steers a transducer array to steer an ultrasonic beam with an AM audio alert to the target zone, where the message is audible only to those within the target zone.
