Here is the interior of a stock 2000 Ford F-150, the most popular car model at the time.
The only actual improvements (not necessarily F-150) since then have been:
* Replacing "eject", "panel & floor", "lo / hi" and other words with pictographs
* Bluetooth connectivity
* Rear-facing cameras
* Upright alcove above radio to place cell phone for navigation
Everything else has been a fucking failure, distraction, or quickly obsoleted.
