Odd, I'd rate it an A most everywhere, and maybe a B+ in roundabouts. Not sure why some people have such a hard time with the Yoke. I wouldn't switch back to the old round wheel if they paid me. Be aware most owners have zero problems with the Yoke, and some owners hate it with a passion and are unable to adapt. I've done 3-point turns plenty of times, and it's no more difficult than using a round steering wheel. Maybe for those that have to keep their hands at the top of the wheel (the dangerous wrist-breaking zone), the yoke is not going to work. It also does take a week or two to adjust when you first start using the Yoke, so those that just use it for an hour or so may not be able to feel the advantages. That said, if you're worried, select the old round steering wheel as there is nothing wrong with it either.
I do agree in a few situations, the turn signals are slightly more difficult to get to, but the Tesla round steering wheel doesn't fix this. I'd say it comes up in maybe 1 out of 500 turn signal activations for me - usually at very low speeds in a parking lot when a blinker is not really needed. I'm used to signaling every turn anyway, so I do notice it. I'm used to signaling when exiting roundabouts and don't find it any more difficult than cars with stalks, which is also tricky as your hands are often not near the stalks when exiting. Most of our roundabouts are fairly low-speed in residential areas. I've not used it on high-speed (>50 mph) roundabouts as there are none around here, so I can't comment on those.
