I don't know if you missed my point or not. Obviously, there is a difference between a cyclist having to pedal harder in order to get back up to speed, and a car or truck having to burn slightly more fuel. It's not about the absolute energy expenditure. It's about the comfort of the vehicle's operator, and the viability of the transportation method as a result. No matter what you think of bicyclists, I don't think anybody can argue that the world wouldn't be a better place if more people rode to work, or the grocery store, instead of driving. We would all be in better shape, healthier, there would be fewer automobile emissions to pollute the air and make people with asthma not able to go outside (used to live in Atlanta, where every darn day was a "smog alert"), and so forth. So my point is that we, as a society, ought to value those rare few who cycle instead of driving, and encourage more people to do the same. And if we are going to do that, we have to acknowledge that one of the reasons people don't ride is that they don't want to get to wherever they're going looking like they just rode in the Tour De France. Allowing cyclists to treat stop signs as yields makes riding much more feasible.
Of course, you ignored the laundry list of OTHER reasons that I posted, why cyclists ought to be able to treat stops as yields: better visibility, better stopping distance, lower overall speed causing more time at the intersection, and, of course, the fact that if the cyclist screws up and has an accident, the cyclist will probably be seriously injured, and the car or truck will not even notice. Obviously, that doesn't hold with an 80,000 lb truck.
