I know breaking the law is unacceptable, but I just want to mention one thing. Assuming you're not informed about the King Street Pilot, if you're at an intersection a a red light and there's a streetcar in front of you. Since streetcars are pretty tall and you'd likely be driving very close to the streetcar, you wouldn't be able to see the no going straight signs until you're already halfway through the intersection.
So a small problem is not being able to see the signs. Maybe adding more no going straight signs should be added a bit farther away from the intersection, so that if you're tailgating a streetcar, you would be able to see it before it's too late. Maybe hanging next to/above the wires.
