Yes, maybe they didn’t know cross rides were a thing, were fatigued and forgot, etc.

This is why people get killed, unfortunately. We had a teenager, riding through a cross ride, and was killed by a driver who didn’t stop behind the line late last year. I visited the spot, and even with a goddamn shrine set up under the stop sign, drivers were still not stopping. I was disappointed, and furious by this lack of care.
