The screenshot was taken from a live stream at 1:30pm on a Wednesday, not during long-weekend rush hour.
The Gardiner, just like the 401 and the DVP, are a traffic nightmare nearly all the time, yet they don’t have bike lanes on them.
This isn’t some strange coincidence or conspiracy.
Car dependency, rather than people riding bikes, taking public transit, or walking, is the real problem causing traffic and gridlock.
I also think that people forget that not everyone is driving because they want to. There are systemic issues that make other means of transportation infeasible for some people, situations, etc.
