[P-hack]

Well I am pro-parallel (mostly parallel) until it looks like *I* or any other willing and trained driver (or a glorified automaton) could get better efficiency with a series. I don't see how that is going to happen anytime soon. Infrastructure and batteries (and other EV efficiency improvements) are likely to become significantly better in the same time frame, reducing the need for hybridization significantly.

I can easily see series taking over in production due to the sheer simplicity/cost of it (at a significant efficiency penalty), combined with all the misinformation/rationalizations, but that is not an efficiency enabling technology for people who know what is going on under the hood. But it is also worth noting that even the volt has adopted a partly parallel strategy before going to production.

"For a successful technology," Feynman concluded, "reality must take precedence over public relations, for nature cannot be fooled."
