Jeeves has a pretty narrow idea of the possibilities, so Trippy figures that the Driver would like a room according to the Driver's Travelocity profile in a hotel that resides somewhere within a few minutes' driving distance from the next half-hour stretch of the current route. Trippy checks a yellow-pages site and the usual group of travel portals, compiles a list of hotels within the zip codes the Driver is currently approaching, and sorts them based on their distance from the route. He queries the first twenty hotel sites to check for vacancies and prices and rules out those which don't have available rooms in the Driver's price range. A few sites don't respond to Trippy at all, so he rules them out after a few seconds as well. Let's Go and Lonely Planet sites.
Unrated rooms drop off the list.
Trippy creates a knowledge tree of the top five, plots the potential course changes and updates the driver. Three seconds after you asked, the GPS tells you it found something. Its reputation is poor. Anything that gets you out of this car and into a clean bed is just fine. Trippy whirls into action again.
