>It's kind of funny that that Cruise beat Tesla to level 4, and the no one noticed, not even the media, even if it's only limited to specific mapped cities.

It is impressive, but this has its problems. Specifically mapped cities and zones don't scale very well. It's less of a problem for taxis and ride sharing but it isn't going to cut it (yet) for people who want to own a vehicle that can go mostly anywhere.

Also, it may be level 4 in some areas, but in other areas it can't operate at all. The levels don't really take that into account and because they don't, the number alone doesn't tell the full story. You can have a level 5 car today under the condition that it only operates on a specific test track that was designed for this purpose. Does that mean it's a level 5 solution? Probably not.
