Nissan is looking to significantly upgrade its Infiniti sedans by adding a steer-by-wire system. Somewhat similar to the fly-by-wire system found in planes, the new tech will mostly dispense with the age-old mechanical apparatus. In steer-by-wire, control signals are transmitted electronically. Since electrical signals are transmitted faster than mechanical instructions, drivers can expect better response time and easier turning.

Nissan has worked around this by including a fail-safe clutch that activates during an electrical event and allow the driver to steer the old-fashioned way. The first vehicles to use the new system are expected to be on the road in the next three to five years.
