As you get into your cab you notice a screen in front of you with the option to obtain a refreshing beverage of your choice. Directly in front of you there is a display that catches your attention.
You are intrigued by this device and make a beverage selection with the touch screen display. All of a sudden the panel behind you opens up and out comes a ice cold beverage.
Pretty cool story, huh?
You end your cab ride mesmerized, having just experienced something new and exciting.
