The lowerratio gives the steering a quicker response — youdon't havetoturn the steeringwheel as much to get the wheels to turn a given distance — which is a desirable trait in sports cars.
Moreover, it can reportedly "reprogram the steeringratio and amplify the intensity and quickness of the steeringresponse" to keep motorists safe, but there's no word on whether or not a retinal scanner add-on will be available to automatically adjust user preferences depending on which driver hops in the seat.
