Hi all, Interesting issue regarding speed, hooning and how the law, society and driving / riding community view all of this. In all the experiences that I have had speed seems to be a greatly referenced and contentious issue, but I feel greatly over exaggerated and implied as the cause of all road evils. Having lived all over Australia, lots of cities and countries in Europe and for a short stint in the US, one thing is abundantly clear. Everybody wants to go fast!! There are some very good and also bad reasons that the law (road) is structured the way it is. Several factors come into play when trying to understand how the architects of road speed have arrived at their conclusions: â€¢ Roads are shared environments with many different vehicle types, using the road for different purposes; â€¢ Complexity of the road environment (eg. Number of side streets, access points and visability etc.); â€¢ Traffic management plays a large part in determining how to control the flow of vehicles; â€¢ Skill levels of drivers / riders is broad, as is their road expectations. This sort of creates a bell curve of skill types out their, and one should aim at meeting the needs of the upper part of the curve (~75% of the population base); â€¢ Surface conditions and provisioning cannot be constantly guaranteed, thus speeds need to be in line with ability to handle broken, uneven or poorly drained areas; â€¢ Roads (unlike tracks) are not closed environments. They have many occasions where objects such as livestock, non-vehicular road users and foreign materials place themselves in the path of a driver / rider, which will limit the overall speed that can be safely negotiated. This is not an exhaustive list. But as you can tell, with all these factors in play, one would want to go as slow as possible to avoid an accident. However, speed may increase ones risk and severity of an accident, but is definitely not the prime cause or driver. No report on roads in the world can scientifically claim this. But unlike driver distraction / awareness / skill levels, speed is the only measure that the authorities can measure you on! Hence speeding is it! Now having lived in Germany for a while and making use of the autobahn (which allows open speed limits for many sections), one is allowed to hit speeds in excess of 270Kph, with little to no more accidents that in 100kph environments such as our highways. So what is the difference? How road users use the road! If the road was a closed system, with traffic maintaining the same goal and driving with a common purpose, then, speed diminishes as a factor more and more. Hence why there are no speed limits in areas of the autobahn. The roads are: â€¢ Mostly straight and very well maintained; â€¢ Have barriers to stop foreign objects entering; â€¢ Purpose built to take high-speed traffic; â€¢ Usually demands that people travelling do so at reasonable speed levels. What causes accidents is the difference in speeds of road users. So if you are doing 100 and traffic is free to go in and out of side streets, turn or look for parks you are in trouble. The more variable the speeds are of users in a given area, the slower the speed limit needs to be to cope with various situations. Because of our congestions, short freeways and highways and surface maintenance and foreign object control. Most Australian roads cannot adopt these extreme speeds. This is why N.T. had no speed limits until recently (but they all know that most deaths were caused by alcohol, not speed (on its own had extremely low death / accident). The ugly is how these factors are hardly used by councils and governments in effectively managing traffic.
