While the steering wheel controls for the touchscreen are decent, this car is missing a pointing device (track ball, touchpad, you name it) for the driver ( or a passenger) to be able to navigate the touchscreen without making the long reach to the touchscreen (which can be dangerous while driving), whether to pick a radio station that is not in favorites, a menu item like energy usage or select the weather off a webpage. Being able to do this with your right hand on the arm rest and selecting would be great. I have used both a wired and unwired usb mouse, as well as touchpad successfully (interestingly, the right mouse button, not the left one, is used to select an item). HAs anyone done any permanent or semi-permanent setup of such a device? I was thinking about mounting it on the vertical sloping service on the front of the arm rest, above the usb ports, but reallized that my trackpad requires a flat, not a sloped surface to operate. Anyone use a trackball? If so, which one? It would be nice if this didnt look rube goldberg-esque. Too bad Tesla didn't think of this. PS, Yes, I know this is unsafe for the driver to take his attention off the road, but if its good enough for BMW and audi, it should be good enough for us.
