The Top Gear have recently asked for examples of silly road signs. One that amuses me are the "Think Bike" road signs: What are you supposed to do if you're riding a bike and you come across one? Spend a few seconds considering how fortunate you are to be riding a bike when all around you almost everyone else is in their metal cages? Check that you've turned the choke off? That you've switched the fuel switch away from reserve? If you ride a bike sometimes, but you're in a car when you see it, there's a chance that you may forget you're in a car and nod to the bike coming the other way, or try to squeeze through a gap that's too wide for a car. Still, I'm glad that the car drivers are thinking of us.
