Re: re : speed check locations
Less road accidents occur on motorways because motorways are safer than minor roads. I would guess that (in proportionate terms) a lot more breaches of speed limits occur on motorways than on minor roads as it is easier to travel at faster speeds on them. Road casualties and breaches of speed limits are not the same thing, although travelling at fast speeds increases the risk of accident.
From my own observation and experience, I reckon most crashes are down to simple driver error. Again travelling fast, drinking etc increases the risk of error, but, on the other hand, it is perfectly possible to kill or be killed in a traffic accident, while travelling 100% sober and/or well within speed limits. Back in the days of asses and carts, people also died in road accidents even though traffic moved at only 10-20mph.
Any attempt to reduce road casualties will fail unless it is aimed at reducing driver error. This is why the penalty points system has failed to do so, despite the apparently temporary statistical blip that indicated otherwise last year.
