It was more than interesting 100+ years ago -- it was the subject of wildly inconsistent, often fear-based (or incumbent-industry-based) regulation.
A vetoed 1896 Pennsylvania law would have required drivers who encountered livestock to "disassemble the automobile" and "conceal the various components out of sight, behind nearby bushes until [the] equestrian or livestock is sufficiently pacified". The Locomotive on Highways Act of 1865 required early motorized vehicles to be preceded by a person on foot waving a red flag or carrying a red lantern and blowing a horn.
It might not quite look like that today, but wild-eyed, fear-based regulation as AI use grows is a real possibility. And at least some of it will likely seem just as silly in hindsight.
For more than thirty years, the speed limit for cars in Britain was 4mph - a self-propelled vehicle travelling faster than walking pace was obviously unconscionably dangerous.
To celebrate the raising of the speed limit to a daring 12mph, a group of motorists organised a drive from London to Brighton. At the time, driving 54 miles in a single day was seen as an audacious feat and few people imagined that such a great distance could be travelled in such complicated and newfangled contraptions without mechanical incident.
For decades, the car was seen as a plaything for the wealthy that served no practical purpose. The car only became an important mode of transportation after very many false starts and against strong opposition.
