Any point worth debating has its merits that can be made within its boundaries, context and analogy are not the same thing.
Context is comparing the risk of accident and injury to other situations it is setting an issue relative to an overall picture, to see what we find is acceptable, it is not analogy, which is a rather differant thing.
Speed isn’t the biggest killer, its innappropriate speed that does the damge, going too fast for the drivers ability in the conditions they find themselves in.
Cutting speed limits does not equal reduced accident rates, though there are circumstance where this may be the case.
Bad driving, mistakes things like cutting across in front of others, driving too close etc, these are all far greater risks, the reduction in speed limits in itself is not likely to decrease the risk.
Its also true that the faster an incompetant driver travels, the more likeley they will be to have an accident, or not be able to respond in time.
The fastest roads in the country also have the lowest accident rates per mile.
An incompetant driver is one who is not capable of reacting to changing conditions, distractions are one way of reducing the overall competance of a driver, remove those distractions and that competance is likley to improve.
Selfishness when you are the only one negatively affected by the consequencies is fine by me, but when it is needless, and when it puts others in harms way it cannot be justified.
Driving in my view need not be risky, the best way to reduce the risks further is to ensure drivers are competant, driver training will reduce accidents and is probably better than most of the enforcement methods, however I can’t see extra training requirements being tolerated in the US and then there is of course the evaluation and delivery of training to look at, which effectively makes universal advanced driver training logistically unfeasable.
