Yeah transformations like that litterally take decades and require public approval. And there absolutly no reason to believe the US is moving in that direction.
So sure, if you want to sit around and think 'I wish I lived in Netherlands'thats fine, but people actually have to live where they do.
And even if you started the most massive program of public and bike infrastructure, it would still be worthwil to develop this technology.
Simpler in concept maybe. In practice, I am not so sure.
Just one example: In SV we voted for a tax increase in 2000 for a Bart Extension to San Jose. If we're (really) lucky, we might get it in 2030 after spending ~$10B. The total distance is ~20mi with less than 10 stations.
Or reducing commute due to remote working in non physical labour?
I feel that there are a lot of simpler ways to address the issues at hand.
