I’m sure if they wanted they could replace the steering wheel with something similar in size to a computer mouse given that the power streering does all the hard work for you however I’d worry about hitting one of those potholes at 56mph and inadvertently going to full lock for a moment just long enough to change 5 lanes onto the opposite carriageway… I guess the size of the steering wheel gives you at least enough control to safely get it on the hard shoulder when the steering fluid drops below whatever level its supposed to be maintained at. Plus there loads of room un there for all the radio controls, cruise control and various others…
