As much as I would love for them to win #1 and stay at #1, I wouldn't want them to ride the subway.
Public transportation is stressful and time consuming. The girls would have to wake-up earlier or push their schedules earlier to accomodate the subway ride to where ever they need to go. Riding in a car they could rest, eat, or do whatever they want in the comfort of someone driving them. I doubt you can do that comfortably on the subway, especially when you're T-ara.
Girls, please reconsider!
