>By following the correct speed limit and following distance, you will have ample time to react to any silly behavior. The problem is that in heavy traffic (e.g. middle of many large cities at 5pm), it's not actually possible to both follow the law and actually make progress towards your destination in a given hour. One example: Try to make a left turn in gridlocked traffic. You're supposed to avoid moving across an intersection until there is enough room for your vehicle, so that if a light changes, you will not block traffic. The problem is that in rush hour traffic, if you actually do that, you will sit there for an hour or more as other cars see the gap and take a right turn, never giving you a spot to turn into.
