I'd say you're pretty likely, given that as well as being distracted you'd
have a different focal distance.

The speedometer/tachometer I've seen like that use a translucent patch that
sticks to the inside of your windscreen, I think it has very slight ridges
(or its 'frosted') on it to catch and reflect the projection towards you.
I'm guessing, since the pictures I saw had a hazey/foggy look where the
patch was.

It gets a bit distracting - I tried doing it using my pocketpc as a
projector (brightness set right up) and gave it some changing mirror images
to project - given time I guess it would grow on you.
