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.
You're such a troll. This is caused by construction.
Not sure why you're getting downvoted. While I agree with OPs point, the screenshot they took is literally where there are construction lane closures along the Gardiner and traffic is backed up at the best of times.
Construction is absolutely part of the cause of car traffic, as is car-dependency. When driving is the most convenient option for commuters to get downtown from the suburbs, then people drive and cause car traffic.
Alternatives such as transit going into the city and bicycles for shorter trips reduce the amount of cars on the road and therefore the amount of car traffic.
Toronto simply does not have space for all of the drivers, construction or no construction. If even 10% of people using transit switched to driving, Toronto would basically need to be bulldozed and replacrd with one big parking garage. All construction does is add to the delays.
