Electric Vehicles are a key part of our tomorrow and how we get there. If we can get all the fossil fuel vehicles off our roads, out of our seas and out of our skies, we'll have a much better environment. This community is where we discuss the various different vehicles and news stories regarding electric transportation.

You don't but it can help with packaging since you don't need a shaft from the rack to the wheel (which is on different sides depending on region). It also means you can have different steering ratios for different situations. You can have a fast ratio while parking and a slow one on the highway. If you have automated driving, the wheel doesn't need to turn when the car turns. Although I think all cars with any kind of autonomous driving still turn the wheel.
We solved that problem 20 years ago with variable steering ratios.
