I feel like this debate is about the concept of a seepometer as a simple number vs a speedometer as a dial.

Your claim that this speedometer was a lot easier easier to read than a normal dashboard, leaves out a bit, that is dependent on what situation we are talking about. In normal driving, I find the dash perfectly easy to read, this concept you have shown be seem to be lacking color coding which would make warning lights less distinct.

One of the best features in modern cars is when they have a HUD, that is fantastic.
