There are lots of behaviors that bad drivers have, but the thing that jumps out to me the most is people who don't treat driving as something they have to *actively participate* in. Far too many people treat their vehicle like a washing machine, meaning they just push a couple of buttons, and the car does the rest. When you hit the road, you are mixing it up with hundreds or even thousands of other people who all have different destinations. Make an effort to anticipate what other drivers are doing, and help others know what you are going to do by *being predictable*. Use your turn signals. Plan your moves ahead of time- if you know that you will be making a turn as part of your route, get into the appropriate lane well in advance so you don't have to do a last-minute lane change that will cause someone else to have to avoid you. Accommodate other drivers if you can. Don't be aggressive- two-ton vehicles are not appropriate tools for conflict resolution. Give yourself ample time to get where you are going, if you can. Not being in a rush will make you more relaxed and less likely to make mistakes that can cause yourself and others inconvenience at best, or death at worst. All of these things simply require that you put some thought into what you and other drivers are doing, and treat driving as a social contract rather than a gladiatorial event where the goal is to come out on top.
