Yeah, I had the same thought. This one seems to be slightly eccentric, so that more of the
wheel is above than below the rotation point. That gives more room for your legs while you're heading straight ahead but when you turn the
wheel. the bigger part goes from being on top to being on the bottom. This may be a problem primarily when parking, as normal driving shouldn't require 180-degree-plus steering
wheel rotation. The flat-bottom
wheel gives more room without going eccentric. So, the top part of the
wheel is still bigger than the bottom but I think it would feel less strange than an eccentric
wheel might. On the other hand, I don't know what it feels like to be turning a
wheel and reach the transition point from round to not-round. That might take a bit of getting used to, also. Realistically, there's probably not that much functional difference between the two configurations in actual use but the flat-bottom
wheel is also attractive and connotes sportiness. I bet it shows up in future models.
