It never ceases to amaze me how many people have no concept of what to do at a 4-way stop intersection. Here it is. Learn it. Live it. Use it. When approaching a 4-way stop, the first car to arrive goes first. If you and several cars arrive all at the exact same time, the car on the right of you has the right-of-way.
It does not mean: 1) Close your eyes and go as fast as you can. 2) Because you have a car over $30,000 you own the road and get to go first. 3) Stay stopped with cars massing behind you and let everyone else go because you do not know the rules of the game. 4) Play stop and go until someone feels sorry for your stupidity and lets you through the intersection.
