Funny thing about horses - apparently when cities moved over to cars from horses they became safer. Because horses spook: and one spooked horse can spook the rest and you get a stampede.
Personally I’d rather be riding my horse from village to village over the hills - and I’m lucky enough to have had need to do that in real life. And I would prefer a city of bicycles to a city of cars. But my point (albeit meant casually) is that most of our solutions have downsides too, even the better-looking ones.
