The only caveat is that the vehicles follow all existing traffic laws and rules for cars and drivers. >“As technology advances, our policies and priorities must adapt to remain competitive in today’s economy,” Ducey said in a statement. “This executive order embraces new technologies by creating an environment that supports autonomous vehicle innovation and maintains a focus on public safety.”
