sometimes it just means it’s too late at night to worry about traffic lights so just treat it like a stop sign.

It treats a green light like a stop sign

Looks like it didn't consider a traffic light in the middle of a block as a thing that could happen.

You mean a green light? That can trick human drivers into seeing a green light.

because they definitely don't stop on green...

When traffic is light (e.g. at night), the traffic light can be scheduled to blink red in all directions. Then it is treated like a simple stop-sign intersection.

I was looking for this response! I am in one of those parts of America where the complete absence of other cars is interpreted as a green light, even if nobody bothers to set them to turn to blinking red/yellow during the low traffic hours.

The stopped driver was obeying the law by not blocking an intersection. The turning driver ignored the second lane of traffic when making its turn.

I've never seen that in the real world. In my area, the lights go RED in all directions. Much safer option.

Nobody expects a red light to be coming towards them.
