This photo submitted by Becky White was shot at 4 sec at f/8, ISO 100. A tripod was used to steady the camera during the long exposure. The light trails from the brake lights add a nice leading line. This photo is a little flat, check your levels and you will find you can improve the detail being careful to not introduce too much noise. I would also suggest using the unsharpen mask to define the detail in the coliseum's exterior. This is a perfect example of taking your time to set up the photo carefully considering the composition.
