Nissan Debuts Steer By Wire System: Can It Make Adapted Driving Easier?

The steering system of a car has started to change quite a bit over the last few decades with the advent of electric assisted power steering, which allowed for much reduced steering effort by the driver.  Recently, automakers have moved to power steering that is completely electric in a quest to improve fuel efficiency and also allowing customizable steering effort for the driver.  In an effort to make driving safer, automakers have been experimenting with steer-by-wire systems that completely eliminate any mechanical linkage between the steering wheel and the front wheels.  Nissan has since previewed their system that is set to be fitted onto some of their production cars in the coming years.  More information after the jump.
