That is not sufficient for self-driving vehicles. The license is the thing that shows "okay, this person seems safe" but then some of the things that keep them safe are the threat of accidentally killing themselves, or being arrested and put in jail for a crime they commit while driving, or the financial penalty of being sued for an injury / damage they cause, or the risk of having their license taken away for errors. If a human being applying for their license was invincible, incapable of being jailed, sued, or having their license taken away, you might expect that our CDL or other licensing processes would be more stringent.
