Interesting! I don't know loads about self driving cars, but my understanding was that Tesla's self driving has done a lot of freeway miles, and not just in a small simple area.
"Tesla miles" are also a misleading metric because they don't factor in all the times the driver has to take back control over the vehicle to ensure safe operation, it's just the sum of arbitrary stretches of self driving that don't represent true autonomous operation.
I agree it's not the same, but that's sort of my point. Tesla's gone for global usage, with automatic deactivation, whereas Waymo has done a very specific area of roads built in a similar style. It's broad vs deep, is what I mean.
Right, so what you really mean is urban vs highway driving. In self driving, urban driving is considered much more challenging precisely because of the characteristics you listed. That's why you see Waymo only now dipping into highway driving because the primary taxi market is all inside busy cities.
