Intriguing, but I'd prefer a data set spanning a few more vehicles and brands. Is this 80% result still true for, say, the Nissan Leaf or the Hyundai Ioniq? Ooh, how about the F-150 Lightning? Does heavier truck hauling have an effect on that metric?
EDIT: They did. The charts were just further down, past the Tesla specific one.
Oh sweet, a nicely collated list of targets for a bunch of these little things.
