I know it's canon, but Jesus, eight meters? How can she go anywhere in public without a dozen people tripping or stepping on her tail?

Because she's a seven meter long bright pink snake.
Also, it probably should be noted that monster-girls aren't common nor fully integrated into society at large. So, especially in a place as demographically homogeneous as Japan, people would be very aware of her. And if such a thing did happen, she (as she follows the rules better than some of the other girls) would be no doubt accompanied by Kimihito who would awkwardly but earnestly diffuse situation.
