Federal regulators are updating rules to accommodate evolving technology in robotaxis. This change may allow some vehicles to operate without steering wheels or brake pedals. Amazon's Zoox vehicles have received approval to charge customers for rides, pending state and local approval.

These vehicles have four inward-facing seats and have been offering free rides in certain cities since last year. Further details on this development are available from the National Highway Traffic Safety Administration and other sources, including the Odessa American.
