As a graphic designer, I know plenty of type phases for products that are created from scratch. Always trying to keep the basic geometric shapes of letters. If you go extreme, an expansion becomes harder.
It all seems to start at the DMC logo creating a futuristic yet basic automotive line.
Take GMC and add the year two thousand on it.

After having created the DMC, they move on in expanding that type phase into a font.

Many fonts are created that way. Problem is that many letters then either do not match graphically or have geometric issues in bonding in words... In other words they look awkward.

If you take the rear bumper DELOREAN and draw lines you will notice it is the geometric expansion of the DMC. However, the "a" and "e' are not a very good match of existing in the same font. You may not mind it now cause you are used to it. Yet the are a bit off with each other.

Like I said, extreme type phase creations do have issues on expanding to further letters.
