Essentially Infiniti is making it so you can mimic the image below on your drive home.

Nissan wants to bring the same tech to cars, leaving behind the purely mechanical solutions currently used to take turns in your four-wheeler. The first automobiles to come equipped with steer-by-wire would be luxury sedans from Infinity. Other companies have incorporated the tech into concept vehicles, but Nissan would be the first to stick it in a production model. The company plans to have the first drive-by-wire cars in consumer garages by the end of next year, with an eye towards a future in which you drive from the back seat using a joystick. Of course, the lack of direct feedback as your tires turn over the road may lead some to cling tight to their mechanical steering apparatus, though, moving to a digital steering system should lead to better handling vehicles.
