What do you mean? Waymo and Cruise have already deployed level 4 vehicles.

If current Waymo counts as level 4 then we need sub-levels for them to have much meaning. They are a long way from supporting something like autonomous driving geofenced to all major US cities in all weather conditions. That big step up is still far behind true level 5, which can handle poorly maintained roads and all of the other weirdness one can encounter outside of major first world cities.

  Waymo offers a taxi service in SF where the cars have no driver. From https://spectrum.ieee.org/amp/full-autonomy-waymo-driver-2652903723 https://spectrum.ieee.org/amp/full-autonomy-waymo-driver-265... > The Waymo Driver operates at Level 4 autonomy, meaning, Waymo says, that “no human driver is needed in our defined operational conditions.” This, Waymo continues, represents “fully autonomous driving technology,” with the Waymo Driver being “fully independent from a human driver.”

    Level 4 means full autonomy over all normal driving conditions. Waymo does not handle complex construction sites like a normal human driver would, a fact verifiable by many thousands of people. It does not have level 4 autonomy. Looks like the article got backlash too because the editor inserted an editor's note in quite large font right in the middle of the article clarifying it.

      > Level 4 means full autonomy over all normal driving conditions. Aren't you describing Level 5? From what I see online, Level 4 means "The car can operate without human input or oversight but only under select conditions defined by factors such as road type or geographic area" Waymo has been operating geo-fenced self-driving cars without drivers present. It may not handle complex situations, but that isn't expected out of L4.

        Level 5 means full autonomy over all known driving conditions. Including dirt roads, etc. Otherwise there would need to be a level 6.

        What's the difference between "all normal driving conditions" (your definition of Level 4) and "all known driving conditions" (your definition of L5)?

        These are not my definitions, they are the SAE's definitions. As anyone can verify themselves by visiting SAE.org
