Great taste but bad execution. It makes a ton of sense IMO to put all the controls on the steering wheel so that the driver never has to take their hand off of it to do something. Physical buttons like this are also great UI for critical controls (unlike touch screen). My only gripe is the layout they went with. Its very disorganized.
For things which are symmetrical within the car (door lock/unlock, windows up/down, turn signal) they should be symmetrical on the wheel as well. Critical elements to driving like the windshield wipers, defrosters, horn and turn signals should all be extremely self evident at a glance whereas amenity controls like radio and AC should be off to the side.
True, controls should be in range without taking the hands of the wheel, but putting buttons onto the steering wheel is only the second best option. I think a better choice are "satellites", as used by Renault or Nissan, behind the steering wheel and below the turn indicator and so on. Those are always at the same position, regardless of the steering wheel's rotation, and I can find and operate them without looking and without taking the hands of the steering wheel. I guess there are some issues with those, too, because they haven't been generally adopted.
