Time the stop lights
You have a great point David, one most of us learn, but don't think of it much while city driving. Mosst city lights are timed that normal traffic flow can generally make it through two lights before having to stop. Some are timed longer that you can make three if traffic is going a bit above the limit. For the brake masher out there, I'd just keep alert to changing lights and figure you have to stop until you get the sync of the lights down. Personally, I try to time the lights that I don't have to use much braking effort through town, don't need the added expense of new calipers let alone new pads every 15K.
