Hi +Jamey Marrs
, it is definitely possible, although you'd need a rooted phone. Check out my blog entry here: http://martin.drashkov.com/2012/02/how-to-make-23-android-megapad.html
, but the essential step in this is compiling the linux kernel with touchscreen drivers. The kernel already comes with a bunch of touchscreen drivers, so it's a matter of finding them and uncommenting them to compile them in. I think it'd be awesome to have a Tesla-like touchscreen in a regular car, good luck with it.
