In a roundabout, I (so as to not generalize how people drive), move my hands on the steering while turning - as in turn and then then when hands cross, adjust and turn more. As in when going anti-clockwise on a U.S. roundabout, initially the right had is on right and left on left, but while turning the hands cross (left hand on right and right on left), so you adjust and lather-rinse-repeat. (I hope I'm making sense).

So: the signal/indicator lever is in a fixed position which can be pressed when the correct turn/exit comes. But if the buttons are on the steering (I'm assuming 2 buttons, touch or actual doesn't matter), their position changes as the steering is rotating so I will have to take my eyes off the road and see where in the steering is the correct button and then press it. For a right exit/turn, the button may be on right, or left, or top or bottom or anywhere on the steering depending on the amount of steering turn.

This is what makes it hard/inconvenient/dangerous.

that makes sense, I am also curious how this all translates to teslas with Yolk wheels where you don't reposition on the wheel (like pictured in the article)

I have my own opinions about that, which I'm going to keep to myself at the moment since I have not actually tried that steering wheel.

For now I think a circular wheel is a better design, but I don't know.

However, the turn signal/indicator button on Yolk steering might be less of an issue, but I feel that it would still be worse than the fixed lever.
