Just about every car on the 400 on summer weekends is multi-passenger. What would an HOV lane achieve?HOVs are useful in specific contexts if you ask me.
locations like the QEW through Oakville were a terrible decision. MTO chose to build 1 HOV lane there instead of 2 GP lanes. Huge waste of capacity for what is a high traffic commuter route.
the 400 though, I’m more supportive. HOVs discourage hyper commuters from Simcoe County but provide the necessary capacity for recreational trips which tend to be multi passenger anyway.
