Technology

... you've never heard of bikes, or legs, or car sharing if you need to transport stuff? you don't need to own a car, it's unnecessarily expensive and bad for literally everything

the only reason one would need to own a car is if it's tied to their job

even if you disagree with this assessment, the technology in this post would almost certainly only be applied in cities, it would likely be restricted to a portion of where trains would be except be far less useful, while taking up tax money that could be used for actually important things

also the US has a higher percentage of the population in urban areas than Europe (82% vs 74%) – the US has a lot less small & isolated villages/towns and historically immigrants to the US always came to large urban areas – and US states are comparable in size, population, economy, and arguably self-governing capacity to European countries (the EU can practically be treated as a soveirgn state itself, in most cases), it's reasonable to say that something that can be implemented in Europe can usually be implemented in the US with a similar level of success, in theory.
