Jon - what a fantastic idea, drive to one destination and then go to another one rather than returning home first. Next you will be suggesting car pooling or something more radical.
Just making the point that sometimes you don't know all the circumstances, and there are circumstances where it wouldn't be a disgrace or lazy or selfish or deliberately polluting to use the car for a short journey.
It would be really embarrassing to present someone who is apparently fit and healthy with their 'lazy/selfish/polluting' award only to find out there were circumstances to justify actions.
Anyway, that's not to say there aren't lazy people. But I wouldn't consider it a disgrace or selfish if somebody cycled to work all week and then did a short journey on a Saturday. I don't think Michael was trying to say that two wrongs make a right - just that everything's relative.
