The current trends within the automotive industry hint towards a shift into Steer-by-wire (SbW) powered steering systems in automobiles. This technology is aimed at replacing the previous mechanical steering systems and promising improvements in vehicle longevity, performance bumps, improved handling, and easier integration with artificial intelligence-driven self-driving (automated) cars. However, the novelty of this technology requires an understanding of its current state of development and deeper knowledge into the extent to which it can replace mechanical steering vehicles. This paper aims to review the current state of Steer-By-Wire (SbW) and analyse it across the parameters that the technology must excel in before SbW is introduced to the mass production of self-driving cars. Moreover, this study will also analyse the current drawbacks of an SbW system and how these can be further polished to achieve desirable outcomes. The paper will provide an insight into how well SbW is really suited for taking on self-driving cars and the true capabilities of the technology driving the system.
