Zoox, Amazon.com's self-driving taxi business, has announced that it will begin testing its robotaxi vehicles in Austin and Miami, Texas.

SK Telecom and Mars Auto will work together to develop self-driving trucks, which are powered by artificial intelligence and powered by the carrier's 5G mobile network, according to the latest memorandum of understanding (MoU).。

An executive at Cruise, a driverless taxi subsidiary of General Motors, said Cruise has also focused on cost-cutting this year as rising losses at self-driving car companies have raised investor concerns.。
