Abstract: Systems and methods are provided for training and suggestion frameworks to improve driver operation of a vehicle. A driver may perform certain maneuvers frequently. Pairing these maneuvers with assigned stimuli may form an association in the driver's mind between the maneuver and the stimuli. A driving scenario may arise in which it would be safer, compliant, more efficient, or more effective for a driver to perform a certain maneuver. If a driver has formed a strong mental association between a maneuver and assigned stimuli, the assigned stimuli may be presented to prompt the driver to perform the maneuver. A driver may still retain ultimate control of a vehicle and may choose not to perform the maneuver.
