I get the impression from some of the replies in this thread that possibly there is some confusion about how hypermiling fits their own use in the city or urban setting. Some of the techniques here are applicable to all driving environments and others are specific to less city oriented driving. For example the tire pressure thing is a no brainer. I have been driving my vehicles at the max sidewall pressure for many years now. You will notice less rolling resistance, better economy, and you will get a lot better tire wear. Simple, safe, easy to do.
For the city driver you still can employ some techniques. Don mentioned don't be "that guy" who is on the brakes, hammer down, on the brakes from light to light. Hypermiling is driver awareness. Watching the traffic, watching the lights, give yourself space, smooth on and off the go pedal. Back off and regen or coast whenever possible. Many times this works very well when watching the traffic lights and timing them. Any time you can avoid coming to a complete stop and conserve any momentum you are going to save energy.
Unlike others here who seem to be concerned about the permanent state of angry distracted and nut case drivers on the road I personally ignore them now. I am going to drive my drive, not worry about the fact that the others around me are insane. I am going to back off early and roll/regen to the light, I am going to easy on the go pedal. I am going to try to avoid coming to a complete stop any time it is possible. If that means backing off really early when I can see the light has changed ahead of me "then so be it" that is what I will do and I will let everyone go flying past me. I will be in the "slow lane" and will be trying to stay out of everyone's path.
I don't just look at this as saving energy, extending range, but largely also the significant reduction in wear and tear on my vehicle. This applies to a ICE, PHEV, or BEV equally.
Also look around for routes to your destination that may be more conducive to your driving. Watch for elevation changes and try to see if you can use them to your advantage. For example many of the local businesses that I frequent for my shopping if I go one way there is a more gradual incline going to the stores, it is a main road with lots of traffic and higher road speeds. However there is another "back way" that is a much steeper climb going to the businesses that is slightly longer way to get there. However I found that by watching the energy consumption even though it is longer I can use that route going back home from the stores and it is largely a coast/regen most of the way home. Plus it is a slower set of side streets with less traffic.
So analyze your possible routes and just think it through. This all works very well for your local driving conditions for locations and areas that you travel often since you know the streets, the traffic lights, and exactly where you are going and where you need to be in the lanes to position yourself for turns etc. It is when you get into less familiar territory that you have to just be situation ally aware and adapt. These techniques are for everyone, not just BEV drivers.
After a while it becomes second nature and I can't personally fathom driving like everyone else. Every time I stomp on the go pedal or twist my wrist on my motorcycle I am very aware of it. It just doesn't make sense, never has, but we all just seem to want to go with the flow. The "flow" is how we got into this mess to begin with. Once you get beyond that "peer pressure" to conform you will stop worrying about what everyone else thinks.
My advice is to just try to stay over in the "slow lane" and let the congo line keep going past. I tell them if they don't like my driving stay off the sidewalk! LOL Most of the time you will see them again at the next traffic light and still just as "angry" as ever. It is their permanent state, don't take it personally.
Hypermiling is not only fun, safe, can save you some money, but you will save your car a lot of abuse in the process. It all adds up to a win for you if you can add some of these techniques to your skill set.
