If your product is unreasonably dangerous and defective, and that defect is the proximate cause of injury to another, you’re responsible.
I know nothing of German law, but from a US legal perspective, it appears that MB is just promising what they already have to do - compensate those harmed by defects in their products.
No, the competition explicitely tells the driver to be ready to take over any second, they promise full self driving only in the ads, but not the contract.
So when a accident happens, the "driver" can be blamed for not reacting.
Mercedes offers full self driving including legal responsibility. You are not oblieged to watch the road or the car while driving (with the current tight limits)
The competition doesn't get to override laws. Tesla may put as many illegal clauses in their contract as they want, if they crash because of autopilot in Europe, they're liable. That's why Autopilot is barely enabled here at all, because they know their software is unreliable.
There are accidents which are not due to defects or unreasonable dangers in the product.
Shit happens and responsibility is not necessarily due to defects/malfeasance/unreasonable risks. There ara honest-to-God accidents. And you are still liable.
