Trying out an analogy: The time is the early 2000s, and the Segway™ is being suggested as the archetype of almost all future personal transportation in cities and suburbs. I don't hate the product, there's neat technology there, they're fun to mess with, but... My bullshit sensor is still going off. I become tired of being told that I'm just not using enough imagination, or that I would understand if only I was plugged into the correct social-groups of visionaries who've given arguments I already don't find compelling. Then when somebody does a proper analysis of start/stop distance, road throughput, cargo capacity, etc, that's awesome! Finally, some glimmer of knowledge to push back the fog of speculation. Sure, there's a nonzero amount of confirmation bias going on, but goshdangit at least I'm getting mine from studies with math, rather than the folks getting it from artistic renderings of self-balancing vehicles filling a street in the year 2025.
