Two quick questions from a new Roadster owner. 1) There's a pretty strong thump when you take your foot off the accelerator pedal, when I assume it's switching to regen braking. Going very slowly, under 10 mph, if I pull my foot it's really noticeable. I can hear it and feel it too. I've got lots of experience with regen braking (hybrids, and this is my 3rd BEV) but this is not what I've heard or felt before. 2) I have clear round stickers on the inside the arms that hold the side mirrors. Just wondering what these would be doing there? The car has the factory pait protection film, but it's hard to imagine a rock hitting the rear-facing side of the side mirror arms... 3) On the little display screen, when driving the top right always says N/A. What am I missing there?
