Sadly it works out for them overall. It only takes a few times of getting to the next light as it turns yellow and they are way ahead while you are sitting there at a red light. Sure sometimes you get to see them when it doesn't work out, but when it works out they are long gone.
Timing traffic lights is a hard problem.
This isn't my experience. Traffic lights are extremely easy to time. Assuming you can see the other lights, watch them. There are a few lights in my city that have a right turn light while the other is red, when the turn light goes yellow that means the red will be green soon. I regularly blow past people sitting at the red while I coasted towards the red and gunned it as it turned green.
They also won't be going anywhere when they get t-boned by someone else doing the exact same thing or straight running a red. It's not worth the risk.
Oh and this isn't a race. The goal is to get to your destination safe and sound without hurting yourself or anyone else. The sooner more people realize that, the safer all of us will be.
I was referring to the city engineers timing all the lights in a city. As a driver paying attention can help, but when you have several square miles of road network, with roads unequally spaced, different speed limits and all the other weird stuff they do in a real city it is not easy. It gets worse if you go from city to a metropolitan area.
I have concluded we will never convince people of that enough to change behavior (they will answer the question correctly when asked, but drive the same) thus i'm supporting transit as much as possible.
Again not my experience. I grew up in Tampa and have lived/worked in other big cities like Charlotte. On the big main roads through town, the lights are usually timed so if you hit one green your golden (outside of extenuating circumstances) if you hit a red you're screwed. They are also usually timed so if you hit a green and do the speed limit you should be fine and have all greens. It's the idiots speeding or crawling that mess that up for themselves or others.
In addition to the above you have big cities like NYC, Vegas, etc that have a central traffic control and will change the timing to account for traffic. In my current city we don't have that but a lot of the lights will go into red/yellow flashing mode where the main drag can cruise through but the cross street should be stopping but is free to go without waiting for the full cycle.
I'm not sure where you have lived or worked but in most places I've lived there have been only a couple of main thoroughfares and the rest all neighborhood roads that take twice as long even with traffic. Where I am now most of the time you are using the interstate to get across town east/west or for north/south you have like 3 options depending on where you are going. Some places you literally can't get to without getting on the interstate or going some long ass way around.
