The traffic mess exists during times like Caribana or when the Gardiner or Lake Shore is closed. It's not a daily occurrence at all.
I don't think QQ should be used as a commuter road anyway, unless there is a problem with the Gardiner or Lake Shore. It's a local road that should be used to access the waterfront. Also, there's enough foot traffic during Caribana and other summer festivals that it would be nice if they could close off the entire street for that weekend. Reconfigure the parking so all lots can be accessed from the intersecting roads.
