Not so useful tip: Ride Fast

This will not work for everyone because not everybody feels like hitting it hard every day and every moment that they are on their bike. But the easiest way to ride in traffic with the least amount of trouble is to ride at a slightly slower pace than the car traffic around you. If you are flowing in traffic, there are fewer obstacles that present themselves. If you are going way slower than the traffic, just the speed difference is enough to make drivers think of you as an obstacle that has to be passed as opposed as something to drive along with. I rather ride along traffic as opposed to slowing it down. If I’m riding in the yellow lines and I see that I can’t keep the pace of traffic I will move over to the shoulder, where cars go a bit slower and where I’m allowed to be slow.
When you are being passed by traffic you have to be on the defensive, you got to make sure that every car that is passing behind you is not trying to make a turn in your path or pull in to a parking spot. Its nerve-wracking to be on the defensive all the time. I would rather be in neutral (riding like 2-3 mph slower than traffic), where drivers will wait for you before they pull out, change lanes, or make that turn. Either that or be on the offensive, where you are riding a bit faster or at the same speed of traffic. Because of your speed you get to choose whether to give the right of way to other cars. And if you remember what I said about momentum, the faster you go ,the more of it you have and the more respect you command, especially at the intersections.
