also if you are doing UNDER the limit not only are YOU distracted the person behind you will be losing their minds in frustration and probably attempt to over take in a dangerous place.
I love the people in the 40 zones around my house.
If you drive at 60 they all look at you and get angry.
THOSE ROADS HAVE BEEN 60 FROM THE FIRST TIME SPEED LIMITS WERE INTRODUCED.
Only in the last few years have they gone to 40. And heavily policed too.
There was 1 fatality in about 50 years.
They are still 60km/ph roads with 40 signs on them, in my opinion
Also with the roads at 40, pedestrians get complacent and just walk out on the road.
