A driving information system that conveys driving condition information to
a driver of a vehicle via a haptic notification seat. A signal
representing a driving condition, such as a lateral position of the
vehicle, is generated. Two haptic signals are provided and regulated in
specific ways to provide the driving condition to the driver: a first
haptic input to the driver from a first portion of the seat, and a second
haptic input to the driver from a second portion of the seat.
