It's like the situations here where there's a green light, but you can't go (safely) because morons are still turning left in front of you even though they have a red arrow and are supposed to stop and wait for the next green arrow. (some cities and/or intersections here don't have/use a red arrow, so you can still keep turning left as long as you're not crossing in front of traffic going the other way and it's green for your original direction).
I've had more than a few drivers behind me honking at me to go when it would be the death of me to do so because of that, but they probably aren't looking at the cars already in the intersection, just the color of the light. Occasionally one will gun their engine and swerve left around me partway into the other lane, nearly scraping other cars, then start to enter the intersection and have to skid to a halt with locked brakes because otherwise they'd hit the cars that are still illegally turning left....
