Don't be daft, I don't think Europe's at risk of becoming irrelevant because they put a greater emphasis on pedestrian safety than the US.
Perhaps just look at a few ancient European towns with cobbled streets with no pavements, no wider than 2.5M and hairpin turns at many junctions. Perhaps it's just a product that doesn't suit the market.
Can you argue, in good faith, that you think Europe, in its current state of regulatory bureaucracy, would have greenlit the deployment of electricity? How about of cars in general? And for electricity - mind you all that risk I mentioned was genuinely at first solely and exclusively for electric lighting. Obviously all the things that build on top of electricity rather required electricity infrastructure to exist first!
