Monetize the car destination pathing. With the site, the user creates their trip via car; businesses signed up for the service offer discounts for their services along the way; car driver wins, and is encouraged to stop at said businesses along the way; business wins, as they can easily market to potential customers and know exactly when they might be passing by, and can offer discounts to lure customers; site makes money from the subscribed businesses in one manner or another (there would be various ways to go about that). Does this service exist? I've never seen it if it does.
