You know, before a couple of years ago I'd never driven around a "roundabout" before. They're getting more common here, but for my entire driving life I'd only done 4-way or 2-way stops. It took me FOREVER to get used to them and not freak out. I'm better now after so much practice, but--although I see how much safer they are--there's just so much to process. Mirrors, mirrors, mirrors =D

On the adaptation, what does the part that looks (to me) like a doorknob do? The rest is pretty self-explanatory ^____^
