Unfortunately, Vancouver, BC was one of the first cities to get rid of its streetcars or trams. Then, never followed up with a comprehensive road network. That doesn't mean to put freeways everywhere, but a good set of major streets & highways, with a provision for the return of trams.
Obviously, SD was able to do what Vancouver didn't. SD just wasn't a dense enough region to have something like BART or an LA Subway. Instead, SD allowed for the rebirth of its streetcars, in the form of a modern tram train or as its officially called, the SD trolley.
In contrast, stubborn Vancouver seems to be set to be one of the last cities to allow for the return of trams. Fortunately, Melbourne, Toronto, Boston & SF..., never totally got rid of theirs like Vancouver did.
