Taking things to extreme, one care driving 1 mile/hour for 500 mile rainy trip, or 500 mile/hour for 500 mile rainy trip, yes you are rushing ahead to go catch the next drop that you wouldn't have run into, goind slower, but you are also not 'back there' collecting the raindrop that the slow care is catching yada yada yada. Lets say the shower is in the form of 5000 streams of water, such as you would see coming out of the tap where enough water is coming out to keep the stream solid, rather than broken up. Number of streams is finite. one every 10th of mile, water is coming down at the same rate in every stream, per your 'raining at the same clip' rule. . . . without putting it to the calculator, i say it minimizes rain drops striking the care going fast.TomDhttps://www.blogger.com/profile/15849663301098055471noreply@blogger.com
