I think a Scooby flash might be a better alternative to the wave.

1. a bit more noticable to other scoob owners
2. a bit less noticable to anyone in the car with you if the other scoob doesnt flash back.
3. if they dont flash back, they'll think theres a copper down the road and crawl from then on.

 

Stick to waving !
Flashing will get you arrested or lynched by the nearest parental group

 

bad idea. i just know that if i flashed instead of waving, someone would pull out on me and destroy my scoob.
When im in my BT van, we wave or flash our orange roof top lights,. . . .hmmmmmm, now theres an idea
