Cake On Board Car Flag

You put all that work into decorating the perfect cake. It maybe even took all night. Now when you load it into your car and start driving, some maniac is driving so close to the back of your car that when he yawns, you can see that he's had his tonsils removed. Now, if there were only some way of letting that Jerk know that you don't drive below the speed limit and take corners like your Great Aunt Tilly just for fun, but because you have PRECIOUS CARGO riding in your car! The Evil Cake Genius has tried using her Spidey Sense to communicate with the ubiquitous crappy drivers around her, to no avail. So, Mr. Evil Cake Genius got her one of these...and now she gets her due respect on the road. So much so, that she's thinking about leaving the flag on her car even on non-delivery days...is that wrong? Double sided car flag measure 7.5" x 10.5" knitted polyester flag with a heavy duty 15.7" staff that's great for use even at highway speeds.
