Did you read the thread?
Imagine driving inside a small roundabout, and planning to exit. The steering wheel is now turned upside down between 180 to 270 degrees turned from straight and level flight.
When you would like to use the turn signal for the exit your fingers can not find the very flat non tactile arrows.
If you try to look, you can not see easy because your right arm is in between (in a left hand roundabout for right hand traffic).
If you anyhow are able to see them, your brain will pick to arrow pointing to the right (as you’re about to turn right) but the yoke is upside down so right means left and vice versa. You are supposed to activate the turnnsignal with the left thumb, both for left and right turns.
Regardless if you could see it or not, the grip you have on the yoke with the right hand makes it impossible to reach the turn signal button with the steering wheel upside down.
Trying to look down on the steering wheel in the roundabout is not very easy to do safe either.
The S3XY button on the other side of the yoke will always be easy to reach. It’s just there, where you want it to be. (Really, no joke!)
Also, for turn dignal right use right hand and for left use left hand. Very easy and logical from first drive.
Even if you need to look and use the other hand, the shape of the yoke makes it easy to choose the right button.
