    So your speed never varies at all? even if the road bends? you don't slow down and speed up?.

    Obviously that wouldn't be possible, so it's fairly obvious that I'm talking about on a straight or a gentle bend.

    and it seems you know your exact speed without looking at the speedo fuck me you are good.

    I'm sorry, are you replying to the right post? Because I said minimal effort, not zero effort. If you need to look down so often that it degrades your ability to drive (your accusation re: speed limits) then you've not reached a safe competency in driving.

    Regardless of how hard you argue if you are looking at your speedo you are NOT looking at the road and at any speed taking your eyes off the road for as little as a second can cause an accident.

    In that case what difference does the speed limit make beyond existing? Are you proposing that there be no speed limits?

    Oh and if the car in front slows down and speeds up I find staying back from them helps you can just lift your foot off the accelerator without braking. So if you stop tailgating you should be ok.

    Who said anything about tailgating? I abhor it. But if you're at a safe following distance you're still going to be speeding up and down when the car and front does, particularly if there's other traffic about. You won't be doing it in a dangerous fashion, but it will still be irritating.

    Strange works very well in france. They vary the speed on both road conditions and vehicles. As to enforce it we could try using traffic police instead of cameras, I am fairly sure that the police are intelligent enough to determine what the weather is like while they stand in it with a speed gun.

    I'm unfamiliar with the system in France, how it's enforced, its comparative safety record or what would be necessary to implement such a system in the UK (or USa or Australia, etc.). Do you have any of that data?

    That's somewhat tautological.

    Agreed.

    Yes you are correct that lower speed limits damage & gives more time to react, but using that logic surely we should just ban cars altogether and just walk after all 2mph is a lot safer than 20mph or 30mph.

    Not really given the law of diminishing returns and the additional factor of balancing up the utility of speed with its risks. Our goal is not safety alone, otherwise we wouldn't by driving at all. Is suspect that on that at least we are agreed.

    Speed causing a minority of accidents is not logically equivalent to speed being safe and people who keep saying that merely harm their case in front of anyone who understands logic and statistics. It may surprise you that I agree that you can't look at speed by itself and say it's dangerous. The issue is relative speed - relative to other traffic by and large. There was a study done by the Federal Highways Agency which showed that going faster or slower than the average speed of traffic causes accidents. It also affirmed that regardless of its role or lack thereof as a cause, speed makes crashes worse. My personal view is that speed limits should be around the natura

    Finding that not all of the evidence presented completely and unambiguously supports a position doesn't necessarily mean the position isn't basically correct.

    Finding that the only evidence presented either refutes the case being made or where it appears to offer any support, is couched in caveats, is pretty good reason to be sceptical.

    Try looking up Aren Cambre's database of speed-related source material, and reading some of the many studies cited there.

    I had a quick look at his site and he seems like a selfish, biased nutjob. He assumes that speed limits are too low, rather than setting out to objectively examine the evidence, wants to be able to drink and drive, thinks driving is a right rather than a privilege, thinks that the only requirement that can be placed on drivers is to protect themselves (i.e. not required to avoid causing harm to others) and so on. Hardly the type to expect unbiased information from. Nevertheless, I've picked out some quotes:

    There is evidence that crash risk is lowest near the average speed of traffic and increases for vehicles traveling much faster or slower than average. The occurrence of a large number of crashes involving turning maneuver partly explains the increased risk for motorists traveling slower than average and confirms the importance of safety programs involving turn lanes, access control, grade separation, and other measures to reduce conflicts resulting from large differences in travel speeds.

    When the consequences of crashes are taken into account, the risk of being involved in an injury crash is lowest for vehicles that travel near the median speed or slower and increases exponentially for motorists traveling much faster. One of the major concerns in all of the studies is the travel speed before the crash. Emerging technology used in mayday, vehicle tracking, and adaptive speed control systems provide the opportunity to accurately and continuously capture travel speed. This technology should be applied in improving our understanding of the relationship between speed, speed variation, and safety.

    When a crash occurs, its severity depends on the change in speed of the vehicle at impact. The fatality risk increases with the change in speed to the fourth power. International research indicates the change in injury crashes will be twice the percentage change in speed squared, and fatal crashes will be four times the percentage change in speed. These relationships are based mainly on speed limit and speed changes on high-speed roads. More research is needed to assess their applicability to low-speed urban roads.

    In general, changing speed limits on low and moderate speed roads appears to have little or no effect on speed and thus little or no effect on crashes. This suggests that drivers travel at speeds they feel are reasonable and safe for the road and traffic regardless of the posted limit. However, on freeways and other high-speed roads, speed limit increases generally lead to higher speeds and crashes. The change in speed is roughly one-fourth the change in speed limit. Results from international studies suggest that for every 1 mi/h change in speed, injury accidents will change by 5 percent (3 percent for every 1km/h). However there is limited evidence that suggests the net effect of speed limits may be positive on a system wide basis. More research is needed to evaluate the net safety effect of speed limit changes.

    Most of the speed related crashes involve speed too fast for conditions. This would suggest that variable speed limits that adjust with traffic and environmental conditions could provide potential benefits.

    In fact the constant pressure NOT to speed causes accidents because I now spend more time looking at my speedo making sure I ain't speeding as I go through the 20th speed camera instead of looking at the road a head of me.

    If you can't maintain a constant speed with minimal effort, you're not a very good driver and certainly shouldn't be going anywhere near high speeds. One of the most basic things drivers learn is how to maintain a constant speed. Few things are more aggravating than being being a driver who keeps speeding up and slowing down.

    Safe speed is what should be encouraged. On a dry, clear day with a well maintained car do 90mph on the motorway. However when it's dark & foggy slow the fuck down and take it easy..

    So speed limits should vary depending on conditions? Whose deifnition of safe speed is going to matter then? How are you going to enforce it?

    Arguing about where the speed would put you is idiotic because it cuts off both ways: go slower and you wouldn't have reached her. The things to consider are ability for involved parties to react, concentration required to drive safely and damage inflicted. Driving faster means you both have less time to react, you have to be able to concentrate harder on what is going on and you'll cause more damage on impact.

    Let me get this straight, you think that the speed limit for a road should be determined by fast a good driver in peak health in a well maintained car go? What do you imagine will happen when someone who doesn't meet that criteria tries to drive at the speed limit? Accidents. You can't have different speed limits for different drivers because that's just not enforceable, so limits have to be set on the basis of what will be safest if the driving population of a whole can go at that speed. Enforcing that limit then has to be done to everyone equally, regardless of driving ability, because police and speed cameras can't determine you're ability simply from looking at the car and it would be absurd to assess your ability afterwards before deciding whether to charge/fine you.

    People who think that the speed limit should be higher because they think they can safely handle a higher speed haven't through through the implications.

    "For example, one study found that a speed limit increase from 55 to 65 resulted in roughly a 3 percent increase in the accident rate and a 24 percent increase in the probability of a fatality once an accident occurred," Mannering said. "But then other studies have contended that legislation-enabled speed-limit increases have actually saved lives. One study argued that increasing from 55 to 65 saved lives because of shifts in law enforcement resources, the ability of higher speed limit interstates to attract riskier drivers away from inherently more dangerous non-interstate highways and reducing how often drivers speed up and slow down."
