Great post! I would add on the subject of drafting that a 3 second following distance should be observed. 1 second is less than most people assess and react (studies show it's closer to 1.5 seconds). Travelling less than 1 second behind another vehicle virtually eliminates any chance of dealing with an unexpected situation. (ADoNA: The Clear Leader in U.S. Driver Safety and Training - a Research Victory) On the range expectations, I have found that rain reduces range by about 15 to 20%. On a fossil fuel vehicle it increases fuel consumption by only 3 to 5%. I think this is due to the amount of water that gets moved by the tires as they rotate. Obviously this is more of a problem at highway speeds where each tire is displacing several gallons of water per second.
