There is a minority of the population that consider cars to be a status symbol, and themselves to be too good to take transit. But the vast majority of people rely on driving because we simply don't have a robust transit system. If you're coming from a place like Milton, for example, using the GO bus is an exercise in masochism. It's slow, it's unreliable, it's infrequent, and as someone who dreams of having proper transit connections to the city out in Milton, the only reason I don't drive is because we're a one car family. Apparently, to the entire province, people who live along the line are total chumps whose time doesn't matter.
So if you remove the highway, without an appropriate expansion in transit service, what do you think will happen to the buses? Will GO 21 buses idling in traffic on Lakeshore, or Queen, along with all the cars that have been displaced from the highway due to a lack of usable alternatives improve the experience in some way?
Sure. But how? We live in a cronyist society where freight lines hold passengers hostage. How can this status quo be challenged? Whatever it would cost to bully Canadian Pacific off the Galt subdivision I would venture is magnitudes higher than what it costs to maintain the Gardiner. And it doesn't help that even this forum is full of people who seem to be against spending any kind of money to improve the situation on the Milton line in the short to medium term, citing that the cost to benefit ratio is higher when you spend construction money on other lines. (Funny, though, how this is not a concern when it comes to building underground subways to Scarborough, Etobicoke, Vaughan, or Richmond Hill).
So, does anyone have any actual ideas? Everyone is against the Gardiner existing, everyone is against paying CP their criminal ransom, and in the meantime Milton and the more northern parts of Mississauga are not getting any smaller, more and people keep moving there, and the best that the shmucks at GO can offer is single decker buses running once an hour (contrasted against a rush hour train frequency of 15-30 minutes), which we are now proposing in this thread should be directed off the highway and waste even more of our time. Hard not to understand why people who use this line might feel like third class citizens.
