Turning right on red is tricky

When driving, there are a lot of things you need to consider when turning right on a red light:

• Is there a vehicle going straight?
• Is there a vehicle turning left?
• Is there a cyclist in your blind spot, or crossing either of the crosswalks?
• Is there a pedestrian crossing either of the crosswalks from either side?
• Is the light about to turn green? If yes, is there a pedestrian about to cross, or a cyclist in your blind spot?

It seems like a huge amount of factors to consider.
