Oh boy, multiple things to say on this.
My mother just died and, RIP, she loved her Baltimore “streetcars”.
First off, streetcars actually already started with horses.
General Motors had a lot to do with screwing the trolley culture. They wanted more business for their ICE model.
Regardless of power source, I would love to have trolleys back. You see where the trolley will be, so you can stay out of the way. And the trolley has to stay on that path, so it isn’t going to foul up traffic by going where driver wishes to squeeze in.
Still living near and driving through my mother’s formative neighborhoods, I still see where tracks break thru the pavement and we pass 1 trolley circle every day, and another circle down a few miles which was opposite the funeral home where we honored her. They still exist and are used as bus(yikes) stops and turn-arounds.
