I don't think US companies are much appreciated in the EU. It
has to do with a certain orange guy, Mr. Krasnov. Just see how
he sold out Ukrainians to Putin recently (again!) aka no info
sharing. (Though, EU countries also suck here - why can they
not compensate for the USA? This is deliberate sabotaging
going on from EU countries as well, though Krasnov far
outperforms them all combined, in a negative manner. He must
get a lot of financial kickbacks for his family dynasty.)
Munich has been a long-standing operational base for many US companies in EU, so they might try just a pilot, but it's not only waymos I see here, also some bmw self-driving test vehicles, also nvidia(?) test vehicles etc. And trust me as a ukrainian myself I know what people think about orange man both here and back there. And europeans are largely sceptical about US companies not because of him but mostly because they're just american.
