Automotive industry has always been on the forefront of innovations and fascinates almost all of us in terms of new vehicle models and cool features. During school days my Auto professor used to scoff at industry's R&D  - citing auto industry hasn't really innovated anything significantly after 'automatic transmission' contribution by GM to its oldsmobile model, and that time the focus now just on styling and looks of the vehicle. I still remember one of my close pals in college actually decided to make a career in auto product design in the early part, and eventually became a known name.
