Actually most automakers do show off prototypes but they usually classify them as one of the following: Concept: Might as well be cardboard cutouts. A physical representation of pie-in-the-sky design with little basis in reality. An example would be the VW ID Buggy. Functional: Usually a Frankenstein vehicle cobbled together from catalog parts with intended purpose of vetting a design or idea. An example would be the EV and Hybrid variants of the Porsche 718 Boxster. Manufacturing: Very close to the final production model but still with a few kinks. Examples would be the Honda e Prototype, or the Ford Mustang Shelby S560 Rivian doesn't give any clear indication of what they're showing off but want you to believe it's the later when it could be the former.
