This is where I think regulation works, to a degree. Most states in the US already ban using handheld devices in a non-hands free capacity (which excludes almost every usage except for navigation and voice-activated messaging and calling), and this should also apply to auto manufacturers with regards to touchscreens in cars. The liability would rest with the manufacturers, since they are the ones installing the touch screens and requiring drivers use them.
