When driving away from a red light, your minivan should not be outrun by the fully loaded semi truck/school bus/cement truck in the lane next to you. The people that are behind you on their way to work know that, too, and that's why they used the lane behind you, and not behind the aforementioned large lumbering vehicle.
Despite common knowledge, you will not, in fact, get a large electrical shock if you use your turn signals to let your fellow drivers know your intentions.
If you run out of gas, and the gas guage reads empty, claiming that "the low fuel light never came on!" will only elicit guffaws by the guy working on your car when he points out that you don't, in fact, have a low fuel light.
If you are the only one at 4-way stop, it is your turn. The guy behind you knows this, too.
When driving on the highway, it is perfectly acceptable to leave the left hand lane to allow faster traffic behind you to safely pass you. You are not a traffic cop, trying to keep people from speeding. Unless you are a traffic cop, keeping people from speeding, then you are. Still, you should let traffic pass you on the left. It's safer that way.
