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't endanger me because their velocity ensures that they're long out of my way by the time I'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. I'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.
