I was wishing for something like this just this weekend. I do my own search through each of the apps every time I look for a ride. You should think about turning this into an app.
Add "the government" to that. After working for 6 years at several large technology consulting firms on government contracts - because of that experience I have even less faith on our government getting things done than ever. On top of the normal big company politics and red tape, government contracting adds more frustration with its own policy, red-tape, and frankly, less than enthused employees. It's one thing working for a company that actually depends on making revenue every quarter - its another working for an organization that just needs to check a box in order to receive a budget for the next fiscal year. Never again...
