I live in a great little village, not on an A road but its a pretty potent rat run at rush hour. The rat run has been created because of council policy elsewhere. when its busy no-one can 'speed' I suppose we have the odd high 'speeder' but the issues are many, various and complex. WE had some of the villagers up in arms about parking outside the school and calling for a speed camera! All I would say to the original poster is that I understand and sympathise but 'be careful what you wish for'
Indeed. This aspect (and many other aspects) of human behaviour can
be rationalised using the Prisoner’s Dilemma scenario. In very short
order, there are two types of behaviour in this model, cooperative and
treacherous. If two people both cooperate, the outcome for both is good.
If both are treacherous, the outcome for both is bad, but if one is
cooperative (call him the Sucker) and the other is treacherous (call him
the Englishman, sorry, just joking!), the outcome is fairly good for the
Traitor, but poor for the Sucker.
I think that’s how it goes, anyway. There is a plethora of interesting
extensions to this game, but in essence, people are often too self
interested to act cooperatively, and suspicious of being a Sucker, so they
tend to defect to temptation and act treacherously (and ask for a
camera), just in case.
Basically, people rationally want to have calm traffic conditions around
where they live, but want free, open roads everywhere else. Although if
they all acted cooperatively (e.g. obey the law etc.), we could have calm
traffic where appropriate, and free flowing traffic where appropriate. But
no-one can quite clinch it, so we have pockets of local resistance (humps,
bumps, bollards, cameras, chicanes, etc.) and general distrust of the
system elsewhere as a result. People bottle themselves behind their own
barriers, yet expect others to open their roads up.
The political system aids this. It is based on geographical constituencies,
so people appeal to their local politician. There is no politician for roaming
groups in other people’s areas. So drivers on the roads are basically
unrepresented when away from their home areas, and thus disgruntled.
Perhaps we should have a “democracy of the roads” to solve all this?
