General Motors’ Cruise driverless-car unit plans to eventually reintroduce its robotaxi service following safety mishaps, but will narrow the focus to one city and shelve plans for the Origin, a GM-built driverless taxi.

Cruise’s new co-president, Mo Elshenawy, outlined in an employee email Wednesday the plan to scale back future operations to one market, a change from an earlier strategy to deploy service in more than a dozen cities, according to people familiar with the matter.
