LAS VEGAS (AP) — Federal regulators are clearing the way for robotaxis to operate without manual controls like steering wheels or eventually even brake pedals as the rules start to catch up to the evolving technology. Amazon's fully autonomous Zoox vehicles got approval Thursday to begin charging customers for rides in the specially designed cars that feature four inward-facing seats once they secure state and local approval. Zoox has already been offering free rides in Las Vegas and San Francisco since last year. The National Highway Traffic Safety Administration also proposed a rule last month to allow robotaxis to operate without brake pedals, but that proposal is still pending. But Morrison said that things like steering wheels, windshield wipers and side-view mirrors aren't really needed in an autonomous vehicle.
