I'm not convinced. The original work for this data was done in the 60's and subsequent revalidation in the 70's only used 114 accidents!
This one is Aussie, recent and has a much larger sample and guess what - no correlation / relationship was found.
Speed Behaviour and Drivers' Attitudes to Speeding - Monash University
there are many different sources and studies.
google 85th percentile.
many studies by different motoring/government groups.
most uni's have done these studies.
Found and added above as you were typing :wasntme:
there i much more data than that. most not australian. and the solomon curve is only half the equationQuote:

Contrary to earlier overseas findings, there was no indication of any increased crash involvement for those travelling below the mean traffic speed in these data. There were relatively small numbers of accidents reported overall in these studies.
Still reading.......Quote:
DRIVER ATTITUDE CHANGE - Driver attitudes towards what constituted a safe travel speed were related to speeding behaviour,

So, what you are telling me is, don't believe the evidence someone put up to support their argument? Do you have any evidence to support this?Quote:
