Looks like San Jose policemen are having problem with the UI of their new in-vehicle Windows-based computer.  Although I haven't looked at the details of their trouble, I think most of the UI problems they listed can be solved by adding a stick-shift input device for selecting common tasks so that they won't have to push too many buttons or the touchscreen.

Beside being effective, the sound and the feel of the stick-shift is a pleasure to use as every sports car and truck drivers know.  Screaming clutch sound effect should be optional of course.
