In my opinion, streetcars suit a function identical to buses. Buses can travel fast in a separate lane along a highway, they can travel slower within traffic. There are a few minor tradeoffs like streetcars cannot pull over to the curb, buses would require an expensive exhaust system in long tunnels. They both suffer from the same mistake when trying to operate a single service across grade separated and at grade, extinguishing any possible advantage by mixing the two types.
Streetcars did have a greater advantage in the past when roads+buses were not comparable to rail+trains on many levels.
Since buses are more flexible and can today take advantage of already built roads, streetcars have a smaller niche limited to mature routes that will not be outgrown by demand with enough ridership to deliver payback from a small operating cost advantage. Their additional benefits are a ride that people apparently find more attractive or pleasing, ability to run routes where space is tight or minimal disruption is desired (eg just 2 rail lines on the ground within grass), and maybe a visible anchor to a route/neighourhood.
Looking at Vancouver, I would suggest streetcars have an opportunity for routes along
main routes that are important enough on their own but will never be upgraded beyond at-grade transit due to a parallel subway line nearby
eg: Main or Granville
routes that have sufficient sources/destinations, yet won't be a top tier route due to lack of feeders/transfers, as is the case with waterfront
eg: 4th/Granville Island/Olympic Village neighbourhood/Science World/Stadium/Casino/Beach/West End/Stanley Park/Gastown
Proposing spending money on Broadway to replace an existing insufficient bus service with an equivalent streetcar line is like proposing a local road with stoplights (ahem, Island Highway... gotta save money somewhere on the project budget for theft... ahem) instead of ever building Highway 1.
What do we need to spend all this money on a Patullo bridge replacement for, let's just install a ferry service. Makes perfect sense, the savings could pay for a hundred times as many miles of new local roads. Local roads can host traffic travelling up to 160 km/h and they cost a lot less than highways or bridges.
Someone should start a localroadsforthevalley.wordpress.com blog
After that, let's get to work on upgrading airports from a few big ones to a larger network of nothing but small ones with a single short runway. localairportsforthevalley.wordpress.com is also available
Finally, localsailboatsfortheisland.wordpress.com should tackle replacing the inconvenient, unattractive and expensive BC Ferries service. All kinds of new routes would be possible, riders would have the chance to enjoy the scenery, and a single boat could go right up shallow inlets while later crossing the Georgia Straight (Salish Sea?) using the outboard motor... it would be a fantastic renaissance
I know of a guy that works for a local university who would publicize the heck out of these ideas. Maybe someone would care to write a letter of introduction and forward these brilliant plans -- it's unbelievable to think that this has not already been done! Mother nature has been wrong all this time, tree tips should be the same diameter as the trunk ... in fact the whole thing should look like a wireframe cube. It's amazing that I can breathe at all with such antiquated bronchial structures in my lungs... or thinking, how could I be thinking using the boorish neural networks in my brain... it's all wrong
p.s.
What do you think of outlawing elevators in Metro Vancouver? We could build more staircases, and have portions of those staircases be escalators.
