They do that to prevent speeding. If all the lights were green you might speed through the downtown core, where there are a lot of pedestrians.

Exactly. If you observe carefully, you'll notice that at night, when there's less traffic/pedestrians, most of those lights turn into green waves for anyone driving at or slightly above the speed limit.

Allowing green waves in a high traffic, high pedestrian downtown area would be lunacy.

NYC does exactly this. Green waves along the avenues to a certain point. Then 10 block chunks of green. Different approaches for different districts.

you can prevent speeding without making everyone stop at every light. Time them so that if you go 40km/hr that you'll make it through the lights.
