The roundabout does serve another purpose for the local population, in that it provides somewhere to exercise as you will see people jogging or running around its perimeter. However, this is not jogging for the sake of just jogging, this is just another part of the deal of the wish they have just made. As the Thai culture is largely based on Karma and good luck, this roundabout is something of a symbol of hope for the people of the inner city, although people do come from farther afield to make a wish.
