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.
