I'd like to hold my hands up "guilty" of doing that!!!!
I've found myself driving around a little slower then usual recently, not intentionally think i've just relaxed a lot lol, i do try and maintain at least the speed limit though.
HOWEVER if someone does get up my ass trying to over take when i'm doing the speedlimit i deleberately slow down and make sure they cant over take (immature i no but theres no reason to get up my ass, especailly when im doing the speed limit)
OH and i also have a pet hate of roads where you give way to one direction cos the road isn't wide enough, people ALWAYS take the piss with them so i've stopped slowing down when it's my right of way, they keep coming through so i end up going through with my hand on the horn, it's not even like i go through at busy times so it wouldnt hurt them to wait!!!
rant over now lol
