KCBS_740 SAN FRANCISCO (KCBS/AP) — Ride-hailing service Lyft says it’s testing a feature that would let users schedule a trip up to 24 hours in advance.

While many commercial taxi and car services let passengers reserve a ride in advance, on-demand ride companies like Lyft and Uber haven’t offered that service. They have said it’s more efficient to dispatch cars when riders are ready to use them. Competing service Uber doesn’t allow advance reservations, although some independent smartphone apps say they can help you schedule an Uber pick-up in advance.

Lyft says it’s now testing the reservation feature with its own employees but promises to offer the service to riders in San Francisco and other cities this summer.
