Impossible? Hardly. I have no issue at all adjusting an adjustable steering wheel to not obstruct the IC.
Acting like "everyone" or even a majority of people can't properly adjust a fully adjustable steering wheel to avoid obstructing the IC to justify looping the top half off is kind of silly.
I didn't say "everyone" or even a "majority", I said "lots" and "many". That's the problem with people discussing things here, they think things must apply to "everyone" and fail to see the perspective of other people. You can argue that there should be a choice between the two options, but it's not fair to completely write off the advantages of the yoke steering wheel for some people.
In my old car (an old Camry from the 90s) the adjustment of the steering wheel is not continuously variable, there are certain clicks you can adjust it to, and at my seating height (height not adjustable), the two "best" positions do not allow for an unobstructed view of the dashboard.
Having the top half gone eliminates that concern and even allows usage of a wider screen without any obstruction, which is getting more popular. I see some of the high end cars like the EQS have continuous screens that go across, and then the top of of the wheel intersects it in the production version, while the concepts show a yoke-like steering wheel that actually takes advantage of that continuous design.
In terms of safety this would be akin to saying that you can't see through the a pillar B pillar or door so let's just make the whole car out of glass for easier visibility. Sure, you can see outward better but the safety implications are far worse than a 2% obstruction in outward view.
I don't really buy that analogy (yet to be demonstrated that the reduction to safety is statistically significant), but think of convertibles (no b-pillar). You lose a massive amount of structural rigidity (which manufacturers have to make up for usually by strengthening other areas, which adds lots of weight, but you still end up with significantly less), not to mention the risks during rollovers (especially for the cars without those fancy pop-up roll bars). Yet plenty of people love them and the insurance institutes say statistically they aren't any more dangerous.
It has absolutely nothing to do with how many u-turns somebody does either. Next time you're in your car go drive around town and look at how many times you turn your steering wheel more than 15-20%.
I'm not saying that you won't occasionally turn a full rotation in daily driving, just that the most frustration you may feel with this design is in u-turns (and things like 3 point turns).
Someone hacked off a Model Y steering wheel just to see what happens and it doesn't seem like that big a deal to me, even when making hair-pin turns (and that wheel is not variable, we have yet to see what this difference means in the Model S).
