I would step back and think about the problem this is solving for people and why your early users are getting value from it. Opening/closing times are helpful, but what about the fastest times in an out of the DMV over the course of a day/week/month? If you are visiting Disney World, when are the best times to hit the popular rides? If you could figure out a way to save people a few minutes a week you could charge for your app, it would likely be popular enough to get good ad sales (GTD Books/Workshops for sure!). As it stands I would agree that it probably wouldn't be a good standalone company, but you are onto something smart.
