Light Sport Aircraft - They all look the same

As of this writing, there are approximately 100 ASTM certified Light Sport Aircraft (LSA) and they all look like they were designed in the 1950s especially the interiors. Why is it that aircraft manufacturers continue to design aircraft with very little consideration for cockpit aesthetics? Are they so focused on functionality that there is no room for aesthetic quality? The same people who buy general aviation aircraft also buy cars and they would never purchase a car if it had the complex interior aesthetics of most small 2 or 4 seat aircraft. If the general aviation aircraft manufacturers leveraged the creativity of car designers, then we would see a paradigm shift in the look and feel of small aircraft. As an example, if an aircraft interior looked like this, wouldn't it be more appealing and approachable for both new and seasoned pilots?
