Thanks, SCW-Greg and Larry Chanin. Those would probably be okay in my neighborhood. The side street by my house isn't very steep and on my side, no house faces it, so there's room for them to pull up right there. In front's a problem due to driveways, the corner, etc. I wonder what the turning radius on those things is, though. I wonder if they check out the area ahead to make sure they don't get stuck, or can they reverse okay? Obsess, obsess, obsess.... ;-)
