To me,it seems people definitely do not think about their actions, be it whatever they are involved in.
There's a short piece of dual carriageway which has a traffic light controlled junction ,which narrows to a single carriage way ,with dual lanes each way.
The lights control a crossroads,the majority 'race' along the outside lane, knowing full well that there inevitably will be a queue to turn right, so will be impeded.
Never mind they just sneak into the inside lane that is going straight on, causing congestion on the way, WHY ,if they are turning right they have a reason to be outside, if they're not, go inside and avoid confrontation.
It's the same in whatever , if the selfish consider there's an advantage in not giving consideration to others, then they take it.
You simply can't be somewhere else before you started, so what rush every thing?
