I have to take issue with this statement: In my experience slow, overly cautious drivers cause much more traffic issues and potential for accidents than people who drive aggressively. A simple example is in a roundabout, if someone happens to approach the inlet at high speed, and cuts me off a little bit, it doesn&#x27;t endanger me because their velocity ensures that they&#x27;re long out of my way by the time I&#x27;m crossing their path, with no action on my part. On the other hand, someone going 5 mph under the limit on the highway causes a backup of traffic, and any time you have multiple vehicles occupying a small amount of roadway the chances of a fender-bender go up, especially when one driver is making a whole lot of people who need to be somewhere sit and wait for an opportunity to pass.<p>I&#x27;d love to see the crash data on aggressive versus docile driving, I think the results would be very interesting as to who is the root cause of the majority of wrecks.
