The thing about Publishing statistics is that we, the readers, don't know how accurate they are. The government can make up numbers to however they see fit.
The worst one is, "motorcyclists have 36 times more risk on the road". Is this an average? Does it refer to city driving? Does it mean if the rider is a douche? The whole scare tactic is stupid.
And sure, going 5kph more may double the risk. But is that for an alert driver or some dumbarse who's not paying attention?
Here's a question for you;
Who's more likely to have an accident?
- A vehicle travelling at 100kph with a driver who is paying attention and has their eyes on the road, or
- A vehicle travelling at 80kph with the driver concentrating more on the radio and looking at the speedo every second?
Ergo, "an extra 5kph doubles risk of an accident" is an incorrect and sly statement - it's a play on words.
Yes, it doubles the distance it takes for one to react but in no way does it double "the risk."
A pre-occupied driver who's not paying attention is where the major risk lies.
