See. This type of "what if" post is why LRT proponents are losing. A bird in hand is worth two in the bush. The subway looks like it will happen. Especially with the coming PCs. Want simple voters like me to support the alternative? Don't offer me a hypothetical. Offer me an alternative plan.
But every non-Scarborough politician who is fighting the subway isn't offering more LRT. Their only argument is that the SSE costs too much and it's one spot. Meanwhile, half the people who ride the SRT every morning are like, "Who the hell gets on at those other stops anyway?" This is the disconnect between transit advocates and the general (and voting) public.
An LRT plan can win. Can't be conditional though. None of this, we'll build this line first and then these other two after everything else. That doesn't fly because then people know that when push comes to shove, you'll cancel those other two lines. See the already cut stops from the proposed LRTs for reference. Offer all 3 LRTs in their entirety as orginally planned. Then watch Scarborough residents march into their own councillors offices to demand they support LRT.
Offer to just build the Scarborough LRT and then Eglinton East in 10-15 years? All you'll get is, " I live in West Hill. What do I care if they build subway or LRT to replace the RT? It's not like this will impact me."
