Ok, a pet hate of mine - which isn't really a pet more of an untamed beast that prowls about my sub-conscience - is people who have their car stereos turned to max and drive around so that it drowns out my music. Personally, I don't want to have to turn my music up just to hear it. So to those who are guilty of such a heinous offense, here is a noiseless alternative you can try, it's called 'Slogan Stickers' and it gets the same message across without half the grief for the other people on the road.
Some Slogan Stickers which will be available:
I have bad taste in music!
I envy deaf people!
WHAT DID YOU SAY?!!
I spent my child support money on my speakers!
