What he was saying is that doing 45 mph constantly over a given distance is more efficient than stop-and-go averaging 45 mph even when factoring in regen. Regen is a transfer from kinetic energy to electrical energy and ultimately chemical energy (in the battery). Since you are well versed in physics you should know that there are inherently losses with every energy conversion. Please be civil, especially when your rude comments are factually incorrect.The stop/go traffic regens the battery. I thought this was well known?
do you even know what the term "Physics" means? Have you ever taken a physics class?
