I'm not in EU so I can't comment if they have a special circumstance that makes there driving test different than elsewhere in the world, but "behaving like a drunk teenager" is not a descriptor I would use. I make use of Tesla FSD every day, 2 -3 times a day. Over the last few months I've had to engage (of my own choosing) twice, otherwise it is completely hands and foot off experience.

I travel hundred miles a day on average on a mix of local and highway, but all major roads in city and suburb.

Or course it would fail a driving test designed for humans.

Humans would fail a driving test designed for autonomous driving too. We don't have the reaction time comparable to computers to ..say.. avoid oncoming traffic or an object/animal on the road within a few milliseconds. Or identify dark objects easier to see in infrared. Or maintain an exact speed, to a few significant digits. Or manually do a good job with traction control.

I'm EU citizen and I've recently tried out FSD during a vacation in US. It drove perfectly. Same with Waymo.
