Funnily enough I find often them to be the same people who do 50 in the 60 zone, but then continue to do 50 in the 40 zone.

GGgrrrrr. I LOATH people like that. There are a couple of constant offenders around where I live, who do 60-80km (and often not even a consistent speed) on a stretch of road that is 90kms. There is no where to overtake and they literally hold up the traffic for almost 1km. When they get to the overtaking lanes at the end of the stretch, they will then speed up to 90-100kms (It happens to turn into an 80km zone there) so that no one can overtake them unless they are going at least 20kms over the limit! It is crazy.

I also loath those people that race me off a red light, so they can be in front, but then slow down to 5km under the limit. I don't mind them driving just 5kms under, but seriously let me get in front first!

I am extremely careful of going the actual speed limit after I got a ticket going 9kms over ($163, that I couldn't really afford), and I often set cruise control, so many people cannot seem to drive a consistent speed. If you are going to go slow, fine, just make sure you are consistent. I prefer hoons to slow drivers, particularly inconsistent ones - because at least the hoons overtake me, and I don't have to deal with them anymore because they are gone.
