1539 ET - Uber Technologies likely has several years before robotaxis materially dent its share of the U.S. mobility market, given the ride-hailing company's rapid growth in sparse markets, BofA Securities analysts say in a note. The analysts expect Waymo, Tesla and Zoox to rapidly scale their production and autonomous vehicle fleets over the next three years, forecasting they will make up 5% of bookings by 2028. The true acceleration in AV rollout could come in 2029, when Tesla could have a significant ramp in AV deployments given growing cybercab production capacity, while Uber has a goal of being the global AV trips leader by that year, they say.
