A car turning on a green light can be simultaneous with the pedestrian's crossing light being green. The driver is obligated to see the pedestrian and wait.

What's not simultaneous is a green turn arrow with a green ped crossing. Intersections in the US are designed so that a green arrow will mean the driver has no conflicts and can proceed.

Not everyone (both drivers and peds) understands that distinction.

I feel like I see a lot of fairly crazy intersections in my US city, where it feels like they break at least one expectation of the simple red/yellow/green patterns from drivers ed. I wouldn’t want to trust anyone’s life to assuming that a green arrow should mean I have the unconflicted right of way, let alone that others are even paying attention to their own signal
