Selling bumper stickers on the net that read "Biker Friendly", seemed like a good idea to me. Just add the KB logo. It achieves little except that hopefully when he as the sticker he will:

A) Indicate before changing lanes,
B) Not run red lights,
C) Let you in,
D) Be aware that you are behind him,
E) Not try to run you off the road in a mindless road-rage fury,
F) Give way to you when required,
G) Move to the left to let you and your mates through on the twisties,
H) Not tailgate you,
I) Not undertake you in a merging traffic lane...(The F*%^#g C*n+s)
J) Not pull a u-turn in front of you, and if he does he will indicate so that you have a 50-50 chance of avoiding him,.
K) Will have his headlights on in low visibility conditions, i.e. dusk, rain, mist...,
L) Won't flick his cigarette butt out the window at you.

Any more??
