Agreed.  The Lower Mainland is one intertwined region that requires a regional plan for vehicle traffic.  The best solution that's been put out there is to toll every bridge and tunnel a dollar or so in each direction, with the proceeds going into a separate infrastructure replacement fund specifically for bridge and tunnel replacement, and not general provincial revenue.  It would redistribute the flow of traffic more evenly (if you've used the Alex Fraser Bridge recently, you know what I'm talking about), and ensure the costs are shared fairly.  
Having said that, don't be fooled into thinking that Horgan wants to "make life easier for people".  Increased carbon taxes are on the way, and if Weaver gets his way, a "mobility tax" might also be in the works.  What these guys give with one hand, they take away with the other.
