The price of toll roads will always force people out of cars, so it's hard to judge purely on that point. Also, in my city, the majority of workers go to the city using transit since parking is non-existant. Only the elites drive in for work. I would guess Vancouver being very dense is even more like this.

Reading the article it seems like the proceeds would fund "sustainable transportation options and other climate emergency actions" which is pretty awful so who knows though.
