why should pedestrians not be showing the same attention when waiting to cross.
Yeah, the consequences of you stopping for someone who doesn't wish to cross the road are that you have to start moving again. This is a minimal cost in time or fuel.
The consequences of you not stopping when someone does cross is ... yeah.
I'm not trying to get down on you but it is pretty much this attitude from drivers which sees their convenience as being of equal importance to my safety which leads me to no longer cycle.
You are in a car. I'm sorry but you can stand a little inconvenience such as stopping for people who don't want to cross at crossings or coming out of your driveway really slowly even when you are running late if it makes the rest of us safer.
Convenience is not equal importance to safety.
