If you've ever wondered the cost differences of flying vs driving to any destination, using a platform like AnyGo allows you to compare prices side by side, which makes planning your trip easier.
It still has a few bugs. It gave me a realistic result for a hypothetical trip between Mundelein, IL and Fenton, MO, but between Mundelein and Washington D.C. it reported it would take 0 time and 0 miles. I used to debug for living long ago so I know it's hard. Good luck!
