So I found an empty parking lot to practice for my road test(finally!) and I began doing the circles left and right. I found the only real way for me to do tight circle is to have my opposite butt-cheek hanging off the seat. I'm used to riding a bicycle in all sorts of weird angles, and I'm not saying I'm uncomfortable leaning the bike that much, would the examiner say anything? In your experience how big of a circle do you have to make on the road test, mine were something like 5 feet in diameter, maybe 4 I'm not sure...
