Put LEDs on car Windscreen wipers, (in the same method as fans that display text) so that when they move backwards and forwards they print messages on the screen - invisible to the driver but visible to the rest of the world...

Add a pad of commonly used phrases to the dashboard - ie. Hey you! - Hey baby! - That space is mine - Cut me up and perish.. etc.

"redundant - a very similar idea already exists on the halfbakery. Any idea involving back windows of cars and LEDs spelling out messages is likely to earn this tag." [angel, Feb 25 2002]

Fair enough if pre-baked... do think its more similar to the fans I mentioned, than to the attached links, as the method to project these lights is already in place with the wipers moving... but fair enough anyhow.

Never been cut up in the car (thank goodness), but as has been implied the premise is quasi-baked and HalfBaked. You can buy configurable LED displays for your car, though I know of none that are incorporated into the wipers. I doubt they move fast enough to get the job done.

Recategorized. This one is at least slightly original, in that it works on the front instead of the back.

Phoenix, just in case: 'cut up' is UK for 'cut off'.

[StarChaser] Thanks, didn't know that.

And I'm glad to see [jutta] took some of us up on the offer to assist. Anything to stay in the game.

Winshield wipers do not move fast enough to do what you are thinking.
