An excuse to talk your way out of a ticket for running a red light. Unfortunately, your speeding ticket will be astronomical.
(If you don't get it, you're probably not going to get it.
Maybe look it up in a real dictionary first).
Officer: May I see your license and registration sir?
* you hand him the materials *
Officer: Do you realize that you were speeding and ran a red light?
You: Well, I'll admit to speeding but I'm not sure about the red light.
Officer: It sure looked red to me!
You: Not to me! Maybe I was going fast enough such that the blue shift rendered the... what I'm assuming was a red light... Blue! (or more conservatively, yellow).
Officer: I suppose it's all relative.
