Rapid Carpool is a carpool-matching service that helps people share rides along major travel corridors. Rather than requiring advance appointments or fixed schedules, it enables riders and drivers to form carpools at designated stations and travel when they are ready. Drivers can accept trip requests with a single tap, making it easier to join a ride along the way.

The service currently lists routes in San Francisco, Washington, DC, Los Angeles, and the Lake Tahoe and Reno area. Promoted routes include Oakland’s Lakeshore area to San Francisco’s Transbay district, and Gainesville to L’Enfant Plaza in Washington, DC. Rapid Carpool highlights convenience, with no schedules or commitments, and offers free rides on most routes. Other routes have low fares, with no surge pricing or subscriptions. Sharing a journey can also help users save time in carpool lanes, benefit from carpool toll discounts, and reduce their travel footprint. Safety features include optional mask preferences and the ability to block unsuitable matches.
