Hi Bob, welcome to the site.
Glad to have another p.eng join the fun. I'm not one, though I prefer the discussions/projects here that are based on science.
You'll undoubtedly run into members who make wild claims and/or don't even really get the basics of the experimental method. Gentle nudging works best, I find.
I've been to your personal Prius site before and appreciate the work that's gone into it. I can trace a line from my first test drive of a new Gen 1 Prius forward to my decision to build an EV.
cheers-
Darin
