Mercedes-AMG GT R concept key fob
This is just a concept, but what if you could control the Mercedes-AMG GT R's imaginary aftermarket suspension via a large display on your key fob? This was from a concept designer anmed Iskander Utebayev. Pretty interesting idea and there's no longer a need for your phone and those manufacturer apps that barely work.
