> That's sort of true in the abstract, but misses the point. Autonomy isn't about "defining conditions", it's about solving real problems. Cars that are L3 only in traffic jams on the Autobahn aren't very autonomous, nor useful. If it's stop go and the system gets above 60kph, it cuts out. If the stoppage is due to construction, it won't work.

> Which is to repeat: it's just a stunt. It's a way to "sound like" they're "ahead" in this area of technology, when clearly they aren't. In fact this car is doing more or less exactly what Teslas were doing in the first version of Autopilot more than six years ago. And note that in all that time, those Teslas haven't been hitting anyone in slow traffic jams on well-maintained limited access highways either.
If it's a race to see which company can develop fully self-driving cars that work in all conditions in the next 5 years than maybe Tesla could be "ahead" of Mercedes-Benz (although it seems to be way behind other companies like Waymo).
However, if we are actually decades away from fully self-driving cars that work in all conditions it is much more useful to have cars that can be trusted to operate without human supervision in limited but well defined conditions, because it is much more useful to be able to have a car that allows you to do something else other than focus on driving SOME of the time than a car that assists you more in some ways but requires supervision ALL of the time.
If Tesla's approach precludes them from making self driving technology work reliably under limited conditions like this, it doesn't matter whether their self driving technology works better (but not reliably) in other conditions, because in practice it won't be as useful as more limited but reliable self driving systems.
Some countries are already requiring the approach Mercedes-Benz is taking here for regulatory approval and based on the number of accidents Tesla vehicles have been involved in its possible that the US could adopt the same approach.
If this happens it will not be useful at all to have a more advanced but incomplete and unreliable self-driving technology in the short term (but perhaps it will be possible to keep developing it without shipping it in cars until it reaches a sufficient level of reliability).
