The present disclosure relates to an intuitive haptic alert system that: (1) Identifies a second vehicle; projects a series of virtual waves emanating from the second vehicle at a source frequency, estimates observed frequencies of the virtual waves at the first vehicle according to the Doppler Effect, and generates a sequence of commands for a haptic motor based on the estimated observed frequencies. (2) Projects rumble zone(s) over road; identifies when the vehicle occupies the zone(s); generates a sequence of commands for a haptic motor based on: an identified occupation and received vehicle velocity.
