I'm not gonna start an argument and certainly don't mean to (well not much)
But shouldn't once be enough to think....slow down enough to not attract attention!
I've been done more than most (3 x speeding bans for 100+, 1 x 6 month ban for 12+ points and about 6 x 3 points). Currently only have 3 points for an infringment of highway code (long story) and I know make sure, where possible I stay well under 35 on my speedo round town. Single lane or bigger...I don't risk it. Certainly not in areas I don't know!
You can't fucking whinge, cause we know what we are doing at the time...so if we get caught. fair cop guv'!
I agree in some areas speed limits don't fit the conditions or area but hey...until they change em....thats what they are!
My brother told me off the other day for doing 50 outside his house, as "...there could be kids playing". I said, but its a 50 limit bro...he said "Well not if I had my way"....and he is currently campaigning for the road to be changed to 30! Whilst he may be right that the road should be slowed down, I technically ain't doing anything wrong by doing the limit am I? Same applies in reverse!
