Individual Utility vs Communal Utility
There was a sad opinion poll this week that showed that now a majority of people think that it is better for people to show pure self-interest rather than enlightened self-interest (whereby people work in part for the common good because that creates a better society)
A good example of how this selfish approach goes wrong was in Birmingham's gridlock tonight. My vegetable oil powered vehicle is also good in the snow. I actually only ended up towing one driver up Mary St in Balsall Heath, but where other cars were stuck I was not.
However, it was not the few cars that got stuck that blocked the traffic generally. It was in fact the failure to allow traffic to flow at traffic lights. Individuals were in such a rush to get home that they blocked the traffic flow from the other side. This was not all drivers, but possibly a good third. That meant that traffic did not flow when the lights changed. This blocked back down to the previous traffic lights (in whichever direction) and gridlock developed.
The road surfaces were actually well gritted and not that slippery although there were isolated problems, but the selfish behaviour of a minority of drivers caused gridlock.
I should really have taken photographs to prove this as we need a different attitude to traffic lights if we are not going to have this recur.
