You would think the tropical islands of Hawaii would be a paradise of profits for rental car companies. After all, the state’s economy is driven by tourism. But what happens when vacationers rent a car, get a parking ticket and fail to turn in the ticket to the rental office? Last month, eHawaii.gov unveiled a first-of-its-kind online service that provides a weekly report to subscribers, identifying vehicles that have had violations during the past 31 days. Government Technology reports that this new service leverages the Judiciary’s site management system and the state’s existing Web portal to help fleet owners save time and labor costs associated with unpaid citations.
