Who is allowed to drive without a driver

California issues three autonomous-vehicle permits, and they are not degrees of the same thing. One lets a company try anywhere in the state with somebody ready to grab the wheel. One lets it run a car with nobody aboard who can take over. One lets it carry the public. The gap between the first and the third is the clearest public measure of how few companies have actually arrived.

A permit to test with a safety driver is close to a formality: 28 companies hold one, most of them suppliers and manufacturers who run nothing resembling a service. The permit that matters is the second, because it is the first point at which the state accepts a car with nobody able to take over, and it is granted street by street rather than statewide. Only 6 companies have it.

3 may carry a member of the public. Everything this site measures about passenger service in California comes from that handful.

The streets, the hours and the weather each one is confined to

For the permits that allow a car to run with nobody able to intervene, the state publishes the operational design domain. It is the most specific public statement anywhere of what an autonomous vehicle is actually permitted to do.

What a permit is, and is not

How to read a licence.

A permit is permission, not activity. A company can hold the widest licence in the state and run nothing, and most of the 28 holders of the testing permit do exactly that. Read the register as who is allowed, and the fleet census or the California record for who actually drove.

This is California only. Texas requires registration rather than a permit and publishes a vehicle count instead of a domain; Arizona and Nevada publish neither in a form anyone can read. So the domain detail here has no equivalent anywhere else, which is worth remembering before treating it as a national picture.

The state maintains this by hand, and each tier carries its own date rather than a common one. A permit revoked between updates still shows here until the page is next edited.
