First: men, don't wear white-framed sunglasses. Just don't. They're for women.
Second: don't put a yellow, diamond-shaped 'baby on board' sign in your car. As George Carlin repled, "Who gives a fuck?" Then, he went on with something about expecting others to alter their driving habits because you chose to bring a child into the world.
I agree. If you are worried about other drivers, take a defensive driving course. Buy a car that can withstand impacts. Only go to the grocery store at 3am. But, please, don't expect others to change because you did.
