Any self-driving car can map out your roads. Saying "no road mapping for your [future] self driving cars" is silly. It could be boiled down to "no camera borne cars" which necessitates no self-driving cars.
And if they don't want our self-driving cars I don't want theirs.
Not about this particular example but we know that’s not how it works; people buy whatever is cheap so not wanting something on invidual level works if you are strong and willing to spend 2-3-4-n x the money, but in general people will just buy. In the 80s many people said it about Japanese cars and yet everyone bought them eventually because cheap and good. Even in China, where many people have the old hate against Japan (far stronger than your feelings most likely as the Japenese did horrible things here), they still drive Toyota etc and they see the issue with that but it’s cheaper than German and better than Chinese, so what can you do.
Also I think you severely overestimate the subtlety of Chinese propaganda.
Europe doesn't have a Google, Facebook, or Amazon, because the major US companies got there early enough to dominate the entire market. I wouldn't necessarily say that that's a good result for those countries.
