The author briefly outlined the incredibly tortuous path of inventors adding every possible technology together over centuries to create a human-powered-vehicle that was even marginally safe and useful on the roads of their time, and then once they finally crack it, the author chalks it up to cultural and social factors. Trust me, as someone who tried to build a ride sharing service before the smartphone, it only seems “cultural and social” in hindsight. Its not. There are a million tiny technological barriers that nobody remembers.
