The 2021 Cadillac Escalade is available with the latest version of GM's hands-free Super Cruise highway driving aid. Fox News Autos Editor Gary Gastelu lets it take him for a ride. General Motors is developing autonomous vehicles through its Cruise division, which is already testing the vehicles on the streets of San Francisco without a driver behind the wheel, but you won't be able to buy one. The vehicles are intended for use in a ride-hailing service the company is hoping to launch in select cities soon, including Dubai where it recently signed a deal to become the city's exclusive self-driving taxi service. The Cruise Origin is a fully autonomous electric taxi GM plans to begin producing soon.
