Try this next time you’re in traffic

Next time you are approaching a red light and people are behind you, leave a car-length or so of space in front of you.  Then, while everyone is stopped.  Move you car up a few feet and stop.  Chances are, the car behind you will do it also.  Keep doing it and see how many times the person behind you will keep moving up.  It cracks me up only because I know that if the car in fron of me inches up, I will involuntarily do it also.

I just did this a little while ago.  I moved-and-stopped about 5 times, and each time, the person behind me did it to.  I was SO in control.
