Here is a sure fire tip to get people to go at a speed at least 3-5 miles faster per hour than they are currently going. First, get into a lane on either side of them. As you are driving, position yourself so that they are close to one car length behind you, but still in a parallel lane to yours. Then, switch your turn signal on to indicate that you would like to be in the same lane they are, but in front of them. You will be amazed at how quickly the other car speeds up to make sure you have no room to merge, forcing you to slow down and get behind them if you want into their lane! Magic, I tell you… pure magic.
