Toyota Pruis and a few other cars have experimented with centrally located instruments.

Personally I find it 'unnatural' to have to glance down and to the side to view instruments.

Part of that is of course the result of many years having the primary driving instruments directly in front, inline with my view down the road. Even after driving a rental Pruis for a week it just took more concentration and effort to shift my view to the side as I looked over and then realign my view with the road as I looked up.

I have not perceived any significant benefits to the central dash location. Certainly there are times when my arm and hand would obscure my view of any display adjacent to the steering wheel.
