I enjoy your writing style, & appreciate your technical knowledge, Richard. I don't think you should include a reference to Social Darwinism without acknowledging that it's thoroughly discredited, was never promoted by Darwin, and has no credible or intelligent following.
I used to ride a 90cc motorcycle, with a top speed of 55 mph on the level, and 70 mph on downhills or with strong tailwinds. When big rigs would pass me, I could tuck in behind them and get sucked up to 70 mph & stay there as long as I stayed within about 30' of their rear ends.
I've found minimal benefit staying 2-3 seconds behind trucks. I use more fuel keeping up with them than I do going my slower speeds.
