Honestly, having lived in Vancouver as well as many cities that _do_ have highways running right through town, I didn't miss that in Vancouver at all. Traffic will suck both ways, and at least Vancouver avoids having ugly, loud highways along its waterfront and through most of its downtown.

Definitely, the best case for cars is to have fast highways that bypass the city, but there isn't a lot of room with that given Vancouver's geography, so it's a lesser-of-two-evils. Beyond cars, public transit and cycling provide a better solution in my opinion anyway.

Regardless... the biggest traffic pain point in downtown Vancouver is the 3-lane (total) Lions Gate bridge.
