Walking and reading.
Driving and reading (don’t act like you haven’t ever done that).
Now you can do it “safer” with Megareader.
Megareader is an eBook reader for any Apple device with a camera and iOS4.
Megareader overlays the text of what you’re reading and displays the live camera view in front of you (or where ever you have it pointed).
What could possibly be better than Megareader?
