This week, Cruise, the self-driving car subsidiary of GM, introduced Origin, a fully autonomous vehicle that has no driving controls whatsoever. It’s meant to be a rolling pod that carries passengers on demand, almost like a small bus or train car. But are companies allowed to operate cars without steering wheels on public roads? Both Cruise and Waymo have pushed the federal government to lift requirements on equipment like pedals, steering wheels and mirrors, and they are allowed in certain conditions. States have their own rules. Although carmakers and safety advocates have been hoping for some clear guidance on what will and won’t be allowed nationwide, Jack Stewart, who covers transportation for Marketplace, says that’s not coming anytime soon.
