I don’t believe you. When the two entities are a wheeled vehicle and a bipedal animal, the differences in locomotion are too different to achieve a sub-10cm clearance.
I'm not questioning what you said, I'm saying that you are wrong.
It's obviously not true that "adaptive cruise control or FSD" could explain your anecdote. Adaptive cruise does not engage in a Tesla unless the road is marked and painted. FSD is not available in Germany. Even if it was, it's far too cautious around pedestrians, it wouldn't allow itself to get within 1 metre of a pedestrian let alone 0.1 metres.
It's also obviously not true that "Tesla used" anything, because the car in your anecdote was owned and operated by a (presumably) licensed driver and not by Tesla.
A better hypothesis for your anecdote is that the driver was French and not that driving a Tesla vehicle somehow reprograms human brains to drive dangerously.
No, the kind of people buying a Tesla are already programmed to drive like this. That's the whole point.
It's the same question like who buy's a BMW or a Mercedes Benz? There's a special type of people the different car makers are aiming at. The same applies to Tesla drivers.
In Germany, where a lot of discussion around cars is happening, just a special type of people buy Tesla.
