Trams, Trolleys and Streetcars

I think they might still have their place, like only a few doing the most busy routes (and free or at least no manual ticketing to further ease the ease of use).

Like within old city centres, imagine as you are walking & one of these bad boys comes by, you just grab it ride for even just a smol distance & hop off in a convenient location & closer to your destination.

Such design doesn't have fixed stops, or rather the whole route is.
