Being born and raised in The Motor City, you might say that cars have always been close to my heart.
Don't confuse that with being able to recite auto stats or recognize makes or models. Hell, it doesn't even mean that I can fix any part of a car... flat tires and brake lights are possibilities, but not 100% certainties based on my skill set. Not at all.
Still, I've been to my share of auto shows through my years as a native (suburban) Detroiter and Michigander. And so I've been to enough in my life to have seen a whole bunch of Concept Cars.

You know, these are the vehicles that might also be known as "dream cars" or design prototypes that haven't come to fruition. And
probably won't. Because
most don't.
Anyone in the auto industry or who's a car show fan certainly knows this.
One of those well-regarded dictionaries with a British name tells me the definition of a "concept" is: 1.) An abstract idea; a general notion. OR 2.) A plan or intention; a conception.
Nowhere in the definitions does it say anything about these definitely coming to market, and changing the way we drive or operate on the roadways.
Basically, these show off new styling or new technology. Many times, they are marketing tools used to assess how people (potential customers) might feel about some new or unfamiliar design. If the public reacts favorably, then maybe the manufacturers will go ahead -- assuming they can even be designed that way in mass production and is something the company can ultimately afford to do. These concept cars might eventually lead to different vehicles down the road (ha!), but clearly any concept vehicle is not ready for the roadways and it's not time to trade in our keys for a better model.
No one who knows what they are talking about would think to pitch a concept car as a sure thing, though. You'd probably get laughed out of an auto show, even if you happen to own a car and drive one every day to and from the office. Some in the auto show world might even think about revoking your access, because you somehow swerved across the center line between "concept car" and" road-ready, driving-approved", and then smashed into ongoing traffic by publishing that thought in a popular auto magazine that many car-lovers read.
