The present disclosure relates to an intuitive haptic alert system for a vehicle 801 that: Identifies a second vehicle 805; projects a series of virtual waves emanating from the second vehicle 805 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 (203 see fig 2) based on the estimated observed frequencies. The system projects rumble zone(s) 802-804 over the road; identifies when the vehicle 801 occupies the zone(s); generates a sequence of commands for the haptic motor (203) based on: an identified occupation and received vehicle velocity. The alerts may be provided via a vibrating wrist watch. The invention enhances driver safety without relying on physical rumble strips.
