Interesting troll post.
If the car is a fully loaded SEL, then you have the capability of using cruise. This will accurately reflect speed when on flat ground, though may be slightly off with terrain.
You can actually set the cruise quite low, and then furiously hit the increase button while also pressing the accelerator, giving you a faux digital readout.
Actually, if this bothers you as much as you say it does, then I think that taking a huge hit and getting back in the general would financially be the best bet for you. Surely then Ford will have learned their lesson
Obvious troll is obvious.
