And this was interesting:

"...as more and more vehicles are hybridized, then the regenerative braking reduces the effect of weight, and hence increases the proportion of the total losses coming from aerodynamics. For a high speed cycle with multiple acceleration and deceleration events this increase can be as much as 44%."

I hadn't thought of that.
For over twenty years, 55-MPH was the National Speed Limit in the USA. Any mention of 'highway' speed implied 55-mph. That began to end in 1995, as States were given permission to take back control of their own course.
