All sorts of animated drawings on the road behind the vehicle... A running dog, road kill etc. Also a line drawn across the road which can have a suitable tagline. Closer vehicles will have ELOHSSA written on the front face of the car.-- Ling, Nov 18 2011 LightLane http://www.lightlanebike.com/Wouldn't be tough to extend this product's functionality.

I am wondering if the road or laser needs to move to make this work. I have seen some laser shows but generally these are shapes and abstract, not depictions of running things. Could you make a move with a bank of concert sized lasers?-- bungston, Nov 18 2011 I like the taglines...
I think simple animations are no problem for lasers and servo mirrors. I've seen an impressive show recently.
Synchronising the animation with the road speed could make the object seem stationary wrt the road. However, if it was stationery, then it would draw itself...
<swimswim> I'd forgotten about that product!-- Ling, Nov 18 2011 random, halfbakery
