PG County Drivers

Is it just me or most PG county drivers just plain suck!!
I am an avid cyclist and every single morning when I ride to work from the Hill, cars with MD state plates from the east, and I have to make an assumption they are from PG County, cuts me off or drive just a little too close to a lot of riders in DC. When they cut you off to make a turn or park or make a sudden U Turn and you yell at them, they act like we riders are in the wrong??!!!
What gets annoying is when they honk behind you thinking they are entitled to the lane......not for sharing with riders.
I am Soooooooo tempted to make bumper stickers that say: "PG County drivers Suck"......
Most African American DC Drivers do the same as well............one of them even yelled at me with racial slurs.......yes, I am not white....
Whereas Virginia Drivers.......the ignorant suburbians they are: they yell something like: "Roads are made for cars"..........

So, I welcome all the rants from cyclists alike who have experienced such incidents.
