Of course that means not only measuring the comfort level of the passenger, but also creating profiles for different passengers - because different passengers have different preferences.
Which in turn makes for incredibly rich hunting grounds for surveillance capitalists.
I floated the question in how far this is *lowering* the acceptance of autonomous driving, but no reply yet.
Addressed at the moment, which is admittedly a lot better than I was worrying.
People questions tended to state that it's less acceptable to collect personal information, while anonymous user states - i.e. your emotional state during a maneuver - is more acceptable.
Contrast this to the above, it implies that a fair amount of data anonymization has to happen to increase user acceptance.
Sometimes I'm glad these things happen in Germany and/or EU with GDPR.
