The 1.7-kilometre 80kph zone between Byron and Sunrise is a serious hazard which puts at risk people who want to cycle or walk into town, and saves drivers only about 15 seconds.
It should be reduced to at most 60 kph.
We humans are very poor at judging the much greater energies and risks involved at higher speeds, and so tend to underestimate the dangers of going faster.
As the Australian Federal Police point out, it takes 45 metres to stop from 60kph, while a car braking from 80kph will still be travelling at round 65kph at the 45-metre mark.
As the ‘Welcome to Byron’ sign says: cheer up, slow down and chill out.
