Baidu's Apollo Go is set to begin robotaxi testing in Hong Kong near the airport, following its operations in over 10 Chinese cities. With safety drivers initially present, the service aims for profitability through scaling and cost reduction, having recently unveiled a sixth-generation robotaxi at a significantly lower price. Currently, Apollo Go provides about 1 million rides per quarter, with plans to deploy 1,000 new vehicles by the end of 2024, positioning it for rapid growth in the coming years.
