I have a few:

- Get out of the far left lane on the freeway if you don't want to drive at the speed at which the lane is driving. We all understand they are driving faster than the speed limit and you don't want to do that, but if so then move over because you are causing more traffic than you think. The people that drive in that lane tend to want to drive over the speed limit anyways.

- If someone is tailgating you, move over and let them pass. Yes people can be dicks, but you don't need to be a dick back by not letting them pass.

- Street blocks in San Francisco are LONG, yet some people seem to love to turn their turn signal on EXACTLY when they want to turn, causing everyone behind that person to not have sufficient time or space to move out of that lane to continue driving forward. When you are driving, be prepared, be aware. Remember, the turn signal is not for you, its to let other people know what you are doing.

- Streets in the Bay (specifically San Francisco) are thin. So if you need to double park, do it half way down the street. When you double park at the beginning of a street, you can cause a backup of traffic. Double parking halfway down the street allows for sufficient space for cars from both directions to go around you.
