Hong Kong taxi trade leaders and Uber have both expressed concerns over a looming quota for ride-hailing vehicles, despite transport authorities vowing to consult stakeholders before setting the final figure. They were responding to the Transport and Logistics Bureau’s submission to lawmakers of regulatory details for the industry on Monday. It pledged to include the quota in the final gazetted document, pending lawmakers’ approval before their summer recess in mid-July. Platforms Uber, Tada, Amap, Didi Chuxing have been operating in a regulatory vacuum, a situation cabbies decry as unfair. Amap is operated by Alibaba Group Holding, which also owns the South China Morning Post. Three major taxi groups told the South China Morning Post that the quota would have far-reaching effects on the market.
