The next GVRD rapid transit line?

[Metro-One]

The Lower Londsdale to Burnaby route makes the most sense to me (though the southern terminus should be Metrotown and not Brentwood). This route will service the greatest number of residents and the widest variety of potential trips / destinations, especially given that Lower Lonsdale to downtown will still have its direct sea bus service (which is already a great link). In the future this line could be extended further west into West Vancouver. All the other routes are too indirect and or service too few residents / areas to justify the cost. This route also avoids the social political dumpster fire that is East Hastings (DTES).

Second best is the blue route because it would expand mass transit downtown, including to Stanley Park, and provide service to both West and North Vancouver, but how much better would it be than the sea bus for many?
