Hardware Kindle as a Heads Up Display

Ah, another idea that I may run out of time to complete.
But I will throw it out here along with what information I have to date.

- - - - -

I have always been interested in having a "heads up display" in my car - I thought it could be useful (for ???).

Recently I replaced my 30+ year old ride with a more modern (8 year old) version.
Gone are many of the mechanical things, now taken place by computerized controls.
(By some, non-authoritative sources, at least 27 embedded computer systems in this model (HCL) car. Hacker City Ltd.)
All of them networked (in fact, three (3) networks of different speed).

Wheee .....
Something to display (I only had to wait a generation or two. :D ).

First thing first - can I use a Kindle e-ink (reflective) display?

This part is easy to try out - buy a commercial piece of "1/2 silvered" mirror -
Place Kindle horizontal -
Place mirror at 45 degree angle -
Look through it.

Duh, even with my lack of hobby time, I should be able to find time to do that. (famous last words).

There are a few known problems lurking in this idea -

In the simplest physical configuration, the Kindle and mirror would have to sit on top of the dashboard.
Perhaps the hottest possible place in a car to place an electronic device - I expect the Kindle to cook (perhaps even melt) when mid-summer arrives here.

So ok, I will only put it in place when the interior of the car is cool enough for the Kindle to survive. ;)

So for my first test of this bright idea -

Can the Kindle reflective display be seen clearly enough during the day (being lit only by ambient light through the windshield) ?

Can the Kindle's front lighted models produce a visible display during hours of darkness ?

I ordered a 5x7 inch sheet of beam splitting glass to find out.
(At about $1 per square inch - ouch)
