One feature universally praised by every Mazda owner is that knob. When 100% of us agree on something?!?! Well... that don't happen every day brother.
I'll never own a car without a knob in that spot.
I totally agree with you. The knob is excellent and widely used by BMW and Audi because it works. It was designed to be simple and keep your eyes on the road. I am a big fan of it.
