You know what, I agree with the cop. I, as does the cop, think that overusing the fog lights in necessary situations will lead to world war 3 so hence unless people REALLY REALLY REALLY need to use the fog lights, they shouldn't. Just "REALLY REALLY" needing to use fog lights to avoid accidents is just inexcusable and out of the question. Shame on you OP for trying to prevent accidents in poor conditions by improving your visibility without affecting anyone else.
And next time it's very foggy or you're up at SFU, think twice before you try to improve your visibility otherwise if you keep turning on your fog lights in these necessary situations, you might just cause world war and mass murder.
