What I wonder most about: whenever the Car gets a minor software update, will they (be required to) do again 10,000 hours of test-driving?

I'm quite sure that those 10k hours are not with a single version but they are already being updated all the time.

A human driver on the other hand similarly also updates his driving behavior throughout his life.

Software and humans are completely different. Humans are, in a way, very fault tolerant. In software, one erroneous line of code can literally crash the car. In a human, one stray neuron will probably don't do much harm.

You can use recorded data in a simulated environment to test new software in an accelerated manner.

The problem is: the car interacts with its environment. When a new algorithm kicks in, the car will behave differently, and as a result the input data will be different, and thus the recorded data will have lost its relevance.
